Материал крепящих винтов - мягкий сплав алюминия, без смазки не рекомендую свинчивать стойки, могут заклинить. Но в целом все нормально, рабочий инструмент. И еще. Уровень по которому выставляется тренога не очень точный. The material of the fastening screws is a soft aluminum alloy, I do not recommend screwing up the racks without lubrication, they can jam. But in general, everything is fine, a working tool. And further. The level at which the tripod is set is not very accurate.
Excellent product half the price of any offering from big brand names. Works very well and the design allows you to thace the laser at any height on the pole without interruption when you use the pressure fit to the ceiling. The case is also very useful and has a little room in it so it can also fit the laser receiver. Highly recommended
