Rated 2 out of 5 by dont buy Not accurate I would not recommend this product if you want accuracy November 25, 2014
Rated 4 out of 5 by The product was up to the usual RIDGID high standards. Right out of the box it was easy to use. Accurate in all indoor conditions that I used it in. Am a construction superintendent and used this tool for all my as built measurements, Every time I pick it up I discover a new feature. As always RIDGID has put together another rugged and useful tool. November 24, 2014
Rated 4 out of 5 by absolutely love it! I bought this product for my husband for his birthday. He says he loves it and that it is a great product. I am not sure why the other review was not so good. He had no issues with it. November 24, 2014

Rated 1 out of 5 by Absolutely awful product Not at all accurate stuff. Cannot be trusted from anybody that needs accurate measurments. When you target towards the sun, it counts whatever it wants. I measured 43cm lenght with this laser 50cm.... I also put a Bosch next to Ridgid targeting a stuff at 6.83m far, both targeting towards the sun and the first gave me 6.83m and the other 6.76m. Fow inside measurments its ok but cannot be trusted I want my money back.... August 22, 2014
