Review on Laser level BOSCH GLL 3-80 C Professional + BM 1 + L-BOXX 136 (0601063R02) by Stoyan Shishkov ᠌

My GLL 3-80 C with a red beam has lines projected on glass levels of different thicknesses. At angle 1 and the angle opposite (3), the lines thicken, and at angles 2 and 4, the lines become thinner. This is observed in all three planes. This is most clearly observed when turning on planes for constructing corners. Lines on the floor of different thickness. An authorized service center for the repair of measuring equipment (Hong Kong) said that they had already been contacted with such questions, but they could not do anything. Their showroom has the same problem (both green and red). I looked at many reviews, but this issue is not consecrated there. We are currently considering a replacement or refund.
