Rated 4.1 out of 5 by 7 reviewers.
Rated 4 out of 5 by Timesaver Device works as advertised, measures angles to .1 degree accuracy. It has an auto shut off feature that preserves battery life. This is good and bad. The good is that it preserves battery life. The bad is that whenever it shuts off, it forgets what the reading was when it shut off. (That is why only 4 stars)You need to "zero" the device and reset the angle. A little irritating, but not a big issue. July 15, 2014
Rated 4 out of 5 by Simple to use. Like the digital readout. Bought this to get accurate angles for cutting miter joints on crown molding and floor trim on a project in an older house where the walls were, in a number of cases, not true. Overall, the tool has performed as advertised without any problems. The reverse angle feature allows measurements of interior and exterior angles without the need to do any calculations.

Rated 5 out of 5 by Easy to read number great tool to find corner angles for crown moulding March 11, 2014
Rated 5 out of 5 by Great tool for crown molding jobs. I like the additional range. Easy to use. Instructions are very clear and you can use it right away. March 27, 2013
Rated 2 out of 5 by worked, then not the device appeared to work at first; but when, and since, I first used it, it became totally dis-functional; sometimes it wouldn't turn on, and when it did it continually flashed a multitude of numbers in only one position as if the circuit board had a short in it; the design and functionality are super, it just became unreliable; I'll be exchanging it for another one, but if it goes bad also, that's it for this product December 10, 2013
