It is convenient that without wires, Use it as the only angle grinder and work fully - forget about it. A 5 Ah battery drains in 13 minutes. The presence of 6 acb does not save. Use as an additional mobile tool - cut off somewhere, strip it quickly and do not pull the wires, especially if it's 80 meters to the nearest outlet - it's super! An excellent device, balanced in weight distribution and, a discovery for me, a very convenient button on.
