NOT SUITABLE for professional use (as explicitly stated in the manual). Average build quality and durability. Built-in 1200mAh battery provides good autonomy. Charging with a micro-USB cable (unfortunately) and not type-C, although it is included. 1/4" thread on the top and bottom sides of the device. The support bracket is relatively practical, comfortably holding the weight of the device at any angle and point of support, as long as it is properly attached to the entire surface of the stable point where you will place it. Satisfactory laser performance in moderately lit areas, barely within the mentioned 15m range. By default, it operates in cross mode, without isolating the vertical or horizontal axis. In well-lit areas and in natural/intense lighting, the performance decreases dramatically (as mentioned in the manual). Small and compact size, does not include a carrying case or anything similar for transportation - can be safely stored and transported, apart from the original packaging. Overall, an expensive product considering its capabilities and quality.

A simple good laser for mainly indoor use and not with a lot of sunlight. That's why I gave it 4 stars because it doesn't perform as well in daylight.

Very good laser level. It doesn't isolate the vertical or horizontal line, but it doesn't bother me. I have it for amateur use and it really comes in handy. The fact that it is self-leveling is a big positive.

Very good, it easily captures levels, intense red color ...
It covers the entire 50sqm ...
Small, easy to use, with a rubber casing for better protection ...
Rechargeable, with good indications ...
It does not isolate the vertical or horizontal line, it always keeps them open ...
Good and economical solution for someone who does not use it daily ..
