i bought a new aeg 58 volt mower, brushcutter and chainsaw about 4 yrs ago. all good for 2 years. then one battery packed up. next the chainsaw died. ended up throwing the mower and chainsaw in the hard waste. still have the brushcutter , it works great.
maybe other brands are better. i now use petrol mower again. the electric mowers have a straight cutter bar. my masport petrol has proper blades like the old victas.
