Picked up this on an impulse buy from Menards the other day. Never heard of the brand, but took a gamble.It was within its stated tolerance (+/- 1/8) when I checked it against my tape. I picked it up for primarily measuring new jobs. I don't know if I'd use it for doing trim, but it would probably suffice in some circumstances. The unit is small, screen is backlit and easy to read. The dot is bright enough even in sunny areas, and with the snow on the ground here.Measures multiple distances, square ft. and continuous measuring. It does not have memory so it you shut it off or leave unattended for 3 min it will auto shut off.Has a LIon battery and charges with a standard micro USB cable. So far so good, but with most new tools, time and use will tell.
