Used it on a few projects now. Very pleased with this product for the price. The only complaints I have are very minor and minor. 1) The \"On / Off\" engagement labeling for the worm gear is backwards. I believe someone else mentioned this too. Does not affect function at all, just causes confusion the first time you're trying it out. 2) If the worm gear is engaged all the way there is a very sticky spot somewhere along it. I am getting around it by only 'mostly' engaging it; when I do that there is no sticking but there is I believe more free play. I can make that work since I'm not doing precise enough work to need the graduations on the handle.
