I work as a finisher, so when my old level broke, it became a problem. I have long wanted to replace it with a newer device, but still did not reach my hands. But when my level broke, I immediately started looking for a new model. The choice fell on the laser level ZITREK LL1V1H. Got it in my hands a week ago. Immediately checked all measurements vertically and horizontally. Deviations are minimal, for professionals it is acceptable. There were no complaints in his work yet.
