I love this thing, easy to use, works awesome. I can't roll by hand to save my life and with this I don't have to, put your cone in and fills from the grinder in one easy step, lightly pack and done.I purchased 1 for myself and then 1 for my daughter. White, so I can see what I'm doing.It is important to use something (I use a chopstick and it works well) to pack the herb into the cone. It does come with cones but they are bigger than I wanted so I ordered raw 1 ¼ cones and they work great, then just store them in the grinder! Super convenient!I'm not adept at rolling at all... This was an amazing find! I'm totally into finding one of their more permanent pieces like made of glass or metal!! Super fun and easy... My hubby who is a master hand roller was wildly impressed at the result and the ease of using this device!!! Highly recommend!!Great gadget for on the go use??Comes in handy when your awY from home, or stuck in trafficWorks well. However product can fall out the bottom.I use this all the time it works perfect. Easy to clean & useGreat product! Holds extra rolls. Grinds very good. I would have given 5 stars if it has a catch all (or a cover) for herb that’s still in the grinder because you need to make sure you put a roll in to catch all. Also it’s plastic which has its pros! But the only con is,… static cling. Also where do I store the pipe brush if not using?!?It makes my life so easy
