This is probably the best hand-crank grain mill , in my opinion. It is very robust and can handle grains very well. There are two different types of grinding wheels included. One for dry grains and one for wet items like nuts.Also, there are optional driver attachments that can be purchased for different power sources, such as a bicycle sprocket or an electric motor.I purchased an inexpensive grain mill earlier which was not able to withstand much grinding. The metal parts were not designed to last very long. I returned that mill and got the Wonder Mill. I am extremely pleased with this decision! If you are interested in milling, this is definitely the way to go!For background, prior to purchasing this I had been cracking my wheat in a malt crusher, then grinding the cracked wheat to flour in my electric coffee grinder. It takes two passes through the coffee grinder, with sifting in between passes, to make flour that is not gritty in texture. I contemplated trying to grind the grain all the way to flour in the malt crusher but it is really not designed for that. Closing the plates enough to grind to flour resulted in a lot of metal filings. It was advertised as a grain cracker, and that is all that it is designed to do. By the way, there are several of that type for sale on Amazon, under different names. The key to recognition is a cast iron body, wooden crank handle, wing nuts holding on the crushing plates, and sometimes a sheet metal extension to the feed. If you read the reviews for these, you will find that they really only crack the grain, regardless of their claims. I am happy with that for cooking as porridge, but not for baking bread.This grain mill really is a flour mill. Before buying it I read the reviews and examined some other models. The more expensive one, mentioned in a couple of reviews here, requires bolting to the tabletop. I didn't want to do that, so this was my next best choice. I did want a hand-operated mill. I want to be able to grind grain even if there is no electricity. It turns out to be harder work than I thought, but neither impossible nor extremely time-consuming. From whole hard red wheat, I ground four cups of flour in about half-an-hour, one pass through the crusher and two passes through the flour mill with the stone burrs. The flour did not look much different from what I got from a single pass through the coffee grinder, but it made much better bread. There was no grittiness at all in the bread. Using the coffee grinder to get flour this fine and consistent would have required eight grindings of one-half cup each, plus putting it all through the sifter and regrinding the pieces that did not go through. I estimate that the time would certainly have been no less. Using the sifter makes my hand ache, and the coffee grinder would have been overheating after that much grinding. With this mill I got exercise for both arms in turn and no pain anywhere. I sweated a little instead of the coffee grinder overheating, which is good for me and bad for it.I broke in the stone burrs with a pound of badly outdated barley. Before I started, the faces of plates did not line up smoothly at the edges. After two passes through the mill, the barley was ground very fine and the stone burrs were riding smoothly on each other. The next morning, I tried to grind our morning oats. I only cook one-half cup of oats for breakfast. One-half cup seems to be too small a batch for this grain mill. I also learned a lesson in cross-contamination, as we had barley in our oats. However, that is not the fault of the grain mill. Our very small batches of breakfast oats can perfectly well be ground in my coffee grinder.I did not see any signs that the steel burrs needed breaking in. The outer edge of the faces of the plates was perfectly smooth, and when these were clamped together the interior parts didn't rub together in any way as to cause metal filings. I tried the steel plates with the wheat. I have to agree with the reviewer who said that the steel plates are very rough to use. There was a distinct jolt every time a large piece of grain was crushed. I did not get that with the stone burrs.Setting the stone burr plates appears to be an art rather than a science. I had hoped for numerical settings so that I could systematize my grinding. However, the single, large, screw-in knob is easy enough to adjust and not wobbly like the pairs of small wing nuts on the crushers. Once set, it stays in place and does not rattle loose like the wing nuts sometimes do. If you err on the side of too coarse, you can always pour your trial amount back into the feed funnel. Since I had no complaints about even my first batch of flour, I won't complain about the lack of settings.The limited lifetime warranty is more limited than lifetime, but in their favor, there seems to be little that can go wrong with the unit.PRO:1. Nicely built one-piece feed funnel. No cracks between sheet metal parts where grain can stick.2. Very secure clamp for bolting to table. Option to bolt directly to table without clamp.3. Good quality flour from stone burrs, two passes. I did this from cracked grain, but there is no reason to believe it would not work from whole. I am just used to cracking it in the malt crusher first.4. Crank turns smoothly and feels as if it will last.5. Burr plates clean easily with an old toothbrush.CONS:1. There doesn't seem to be any way to remove the feed auger for cleaning. The mill is heavy enough that I am not inclined to unclamp it and shake out the grain left inside on a regular basis. According to their website, the newer model of this unit comes with a long handled brush, similar to a paintbrush, for cleaning the plates and the auger. The model sold here doesn't come with that brush. I don't see how that helps anyway, unless you pick up the mill and tilt it so the grain falls out of the feed channel, in which case you don't need the brush.2. The handle on the crank turns very stiffly. If you don't grip it tightly, it tends to turn in your hand instead of around the crank and could cause blisters after long use. I actually had the best experience with it after I washed my hands once and did not dry them. The handle turned smoothly in my hand rather than around the crank. This isn't right nor necessarily reproducable.3. Flour spews out sideways from the plates. The faster you crank, the further it spews. According to their website, the newer model of this unit has a shield to deflect the flour downward, but the model sold here doesn't have that. I have been using the non-stick liner from an old electric rice cooker to catch the flour. This catches most of it, but not all, and I have to watch my speed of turning at that.Produces the most wonderful tasting flour ever.Assembly is confusing, with several different pages that each provide different instructions. Luckily, the company's customer support number provided prompt and thorough help.Here's what I wanted in a mill:1. The ability to grind very fine flour.2. A mill that could be cleaned well enough to grind gluten-free flours after grinding wheat.3. A hand-powered mill to have on hand for emergency preparedness.Since I couldn't afford 3 separate mills, I settled on the Wonder Junior Deluxe.Here's how it met my requirements:1. This mill can grind a very fine flour, but only if you grind it coarsly, then again on a finer setting. The problem with this is the second grind takes a VERY long time. Doing a single grind, I was able to grind 4 cups of hard red winter wheat into bread flour in 20 minutes. I was grinding like I was trying to set a world record though, just to see how fast I could physically grind wheat. I do not grind this fast on a regular basis. For comparison, I'm a relatively small female, and not in the greatest shape, but even my husband had trouble keeping up that pace. My four-year old can't even turn the handle. We thought the single-grind flour made gritty, heavy, bread, so I've been double grinding. It takes me about an hour and a half to grind the same 4 cups of wheat berries into fine flour, putting it through the mill twice. I do the first grind as coarse as possible, but still cracking the grain, hoping that the larger particles will feed through faster.2. This mill can be cleaned well, but I had to use a Waterpik to get all of the wheat out of the auger. At least this mill can be washed - some can't. It is not very easy to wash, and I have to let it dry overnight before using it again. However, if you're not worried about gluten contamination, you don't need to do much more than just brush it off between uses.3. I suppose this mill meets my "emergency preparedness" requirements. If I couldn't afford flour and had to grind my own, this would do the job, provided I had enough time. If I didn't have electricity, it would still work.After getting frustrated by the amount of effort and time this mill took, I decided to try to hook it up to a foot pedal. I took apart some old exercise equipment for a pedal and sprocket, bought a bike sprocket and chain, and made a contraption. It works, but it's still really slow to grind flour this way. I found pedaling lying on the floor took way less effort than sitting. At one point, I gave up on this mill, and bought the Kitchenaid grain mill attachment for my mixer. After a couple of months, this attachment broke my mixer, so now I'm back to grinding flour by hand (and now kneading dough by hand too!).Some other thoughts:The mill seems to be built well. I've been using it regularly, and nothing looks like it will break any time soon.It is capable of grinding rice flour almost as fine as store bought flour (again, double grinding).It does not make consistently sized coarse meal. You get a mix of sizes, from fine flour to large pieces.I haven't found much use for the steel burrs. Using them on grain, it is difficult to turn the handle, and it jerks as grain gets caught in it. I tried making peanut butter with the steel burrs. I had to use a knife to chop the peanuts into approximately quarter-peanut sized pieces to get them to feed through. It did make a nice creamy peanut butter. However, it took so long and made such a gooey mess, I don't think I'll be trying nut butters again.It took grinding 15-20 pounds of grain to break in my stone burrs, not the "pound or so" that the manual says. I started throwing away the first couple of spoonfuls of flour, and I stop grinding when there was still grain visible in the auger. I don't know if that made the difference, or if the burrs just finally broke in. At least there are no more pieces of sand in the bread now.So from what I know and have read, here are my recommendations: If you can afford the Country Living mill, buy it, not this mill. If you want to grind a lot of flour (and have electricity), get an electric mill (but not the Kitchenaid mill attachment!). If you need a hand-powered mill to grind fine flour, and this mill is all you can afford, it does work; it's just really slow and requires a lot of effort. If you are preparing for a complete disaster, consider whether or not you are really going to need to grind fine flour in that situation. For much less than the price of this mill, the Back to Basics mill will make coarse flour perfect for making hot cereal (or even slightly gritty pancakes or flatbread).I'm on a tight budget right now, and justified the price of this mill with the money I could save on bread, so that's why I've been crazy enough to keep using it. What I really need now is two electric mills - one for wheat, and one for gluten-free grains.**UPDATE**I bought and installed the re-designed (new in 2011) auger. It works very well on things like corn and beans. However, now I can no longer grind wheat into fine flour, even when I double grind, and the handle is harder to turn. I have to add half white flour to bread to keep it from coming out a brick.My original auger got rusty from washing the mill (so be really careful if you wash it - or better yet, don't get it wet). I am so unhappy with the new auger that I'm going to clean the rust off my old one and re-install it. Unfortunately, this is not an easy process, so I can't switch back and forth between the augers depending on what I'm milling.Then only drawback as the confusing assembly instructions. I think I still have a washer leftover that I'm not sure where it was supposed to go. HOWEVER, it comes with TWO augers and millstones! One of them is for finer grinding, like wheat flour, etc, while the other is for more oily things like coffee and peanuts for peanut butter and fresh ground coffee! It's less expensive than other high-end grinders on the market. There are also accessories available to make grinding less laborious and faster! I could sing this mill's praises all day! Highly recommend this, both for quality and versatility!It works. And so will you! Needs a good motor. The drill idear burns them out havent yet found one thatcan take it. Went up to 1500 wats burned out imediatly!
