The lens is very powerful, especially for areas where light is sufficient. The wrench is satisfactory but not strong enough for heavy-duty work. The nail gun is also good, specifically used it to demolish a cement wall with the chisel and to drill holes. The wheel for the tasks I need is very good. What is inadequate is the drill, which often struggles to penetrate even soft metals, and its bits loosen with the slightest touch, which is annoying. The batteries last up to 2 hours each, and the carrying case is very convenient.
