Review on Klein Tools 935AB4V Magnetic V Groove by Robert Ryokan

There are quite a few levels. As an electrician he is simply the best. Had to buy a new one after having taped the old one to the counter and plastered it with plasterboard before getting to it. The bottles are easy to read. Has a bubble for all 4 corners that we use. Magnets are top notch. I have made many comparisons with others and the client is the strongest. By carefully positioning the magnets on a plane, they stay in place. Plus a mounting screw to prevent dog paws. I've dropped my old one a few times. After testing at another level, it always stayed accurate. Save your time and money, skip the rest and buy this one.
