Review on 📏 Laser Measure 393Ft - LOMVUM Laser Tape Measure Tool with M/In/Ft Unit Switching, Backlit LCD, Pythagorean Mode, Distance, Area and Volume Measurement - Carry Pouch and Battery Included by David Moreno

I really like this product, but both the original and the replacement had dust under the screen. I added a star because I was able to remove the dust myself but probably somehow voided my warranty. I first removed the four small Phillips screws and then carefully pryed the bottom off the left side, being extra careful not to damage the tape on the right side, which required me to close that side and open it like a door. Then, with the lid partially open, I used a lens cleaning tissue to remove dust. It was stressful and difficult to remove the dust without adding more dust. Please add a small, dust-free booth to put your hands into the assembly line. I can't believe this product is IP54 rated.
