I use it myself, I don’t give it to others, since the tool is not cheap. I sawed and sawed rebar and plastic with it. Disks are not a problem to replace, I advise you to look at what you take and for what work. The casing on it rotates to work from any position. For construction work with metal, a very convenient earpiece. Its pros: The eyelet is light and comfortable for working at height. Discs are very well fixed, do not dangle. The motor is strong, so sawing is no problem. Cons below: Batteries are sold separately expensively, if you don’t have suitable ones, it’s better to take them immediately complete with them and charging.
