Very powerful machine. It has three speeds and I usually use it on the second one. I haven't found anything it can't do compared to gasoline-powered ones. It comes in the package with a trimmer head, three plastic blades (something between a trimmer head and a disc, which has been very convenient for me), and a disc. I haven't timed how long the batteries last because they run out before you get tired. Of course, I don't have the genuine ones. I have bought bigger ones from eBay. Two pairs of batteries (9ah). Each battery costs about 60 euros and the charger costs 40 euros. Its main advantages, compared to gasoline-powered ones, are that it starts immediately, doesn't smell of gas, is quiet (almost), has lower operating costs, and I imagine maintenance costs as well (because I haven't had it for a long time)

Incredibly powerful but with all the known benefits of the battery. It has been tested in extreme conditions on very tall and tough grass and did not sweat. However, its power relatively quickly consumes the battery. About 20 minutes with nylon cord and almost 30 minutes with the blade (5Ah). I believe that in more normal conditions it will last much longer. To enjoy the work, you definitely need a second set of batteries. The ADT feature that automatically adjusts speed and torque is very useful.
