I tested this tool shortly after Rings & Things added it, and liked it enough to buy one for myself. It's not a traditional engraver, but it's fun and easy to use, and you can get a nice sparkly finish wherever you use it. It's sort of like "spinning sandpaper". I use it for general texturing and adding "tooth" to a metal surface. My only complaint, is that the "on" button is a bit wimpy so it can turn on by itself when you transport it. So I recommend that when you put it away, first remove the batteries and keep them separate so it doesn't wear out the batteries while you are driving with it in your toolcase. Also, don't pack it next to heavy hammers or you may damage the tool.
