I purchased this tool about a month ago and it was amazing. I have been trimming my horses for the past 15 years and this is the first thing I have found that is just amazing. It takes all of the hard work out of trimming your horse. After the 5th horse it started making a weird noise and I instantly thought great its a piece of junk so I considered just sending it back through amazon but instead I called the company that made it and their customer service was outstanding. They explained that there was an issue with a batch of gears they got in and that they only discovered it from people calling. They were working very hard to rebuild all the tools with the bad gears but a few had already been shipped out. She walked to the back and had a brand new one to send out to me before I even got off the phone. she was very apologetic and thanked me for giving them the chance to make it right and said they strive very hard to make sure their customers are happy. I received a replacement within 2 days! Good Honest American company.
