Review on PowerSmith PLTL320: The Ultimate Torpedo Laser Pointer for Precision and Accuracy! by Kyle Kriglstein

Works perfectly. Batteries are easy to install. The level is pretty good. Then, after reading the instructions in the fine print, it says. "Indoor use only", which is not mentioned in Revain's advertisement. OK, four stars. I've used it outside and it's not as powerful as my old level (which died after 20 years because the batteries leaked and corroded killing it). But in my case it worked (about 10 feet). I wouldn't expect the beam to come out more than 20 feet. So I'm glad I bought this level. I did what I had to do.
