Mine's a fancy-pants Stihl battery mower, but it works quite well and has been doing so without problem since I bought it ~4 years ago. The other battery stuff from the same brand (trimmer, chainsaw, kombi-tool) have the same story.
Stihl is a commercial product (mostly). They design for people using them as a full time job. You pay the price for quality.
