Bests & Worsts Reviews from Amazon

These are an amazing deal at the price, so definitely recommended for accurate woodworking. When I first had them, I'd find that they'd turned on in the case and had a dead battery when I needed to use them. So I bought a pack of 12 batteries to make sure that never happened again, but then I found that they weren't turning on because of being bumped in the case, but because the jaws had moved. They're designed to turn on automatically when they see any opening of the jaws, rather than having to push the (pretty tiny) on button. So now I turn the locking screw before I put them away and I haven't had the problem since. Anyone want to buy 11 batteries? :)
