This is not a laser rangefinder, but a miscarriage of Chinese underground production, not otherwise. You can buy it only if you want to annoy someone well, and to such an extent that the person then sits on tranquilizers for another month. I'll start with the positives: it holds a charge really well. You can work with it all day and the batteries will last. Beautiful, comfortable to hold in your hand (unless, of course, you have the Hulk's paws there). And now the cons. Of course, you can run back all day with it, only by the end of the working day my head began to spin and a terrible dryness of the eyes appeared (no, I didn’t look at the beam on purpose). The ophthalmologist said to throw out this muck and use something normal. Now I have a question, does this miracle have any eye safety document. The building is beautiful, of course, but until the first day at the construction site. Because a couple of days of rubbing the laser on plaster and paint from the body will gently whisper to you "goodbye, losers, I'm off." Seriously, this coating peeled off around the edges just right away. The third and most nightmarish minus for me personally is the silicone button. She flew off after a week of active use. The back cover of the case - on the first day. I really don't know how anyone can design, assemble and sell such a disgusting product and would never recommend it in my life.
