Love these things I bought 4. I had a few at Harbor Freight but they took troublesome CR2032 batteries (3 for each device), AAA batteries are easy to find. Works just as well as Harbor Freight or Johnson (?) which I bought at bargain prices for over half the price. The only thing I would like is for it to be at the level of the back as NONE of them have amazing viewing angles. Although this and Johnson (?) have backlighting, really good backlighting. Excellent light diffusion. Not like the cheap three LEDs that glow on the display, almost like a regular backlight. Definitely recommend, ideal for leveling a 3D printer bed.
