good mower battery life of approximately 20 minutes (for me ca widely enough to make beard and hair) allow 1 hour minimum charge or you will run out of battery in the middle bay of the cut (it feels a bit silly about it). Point +: the teeth of the trimmer are arondi which is very good because a lot of lawn have sharp teeth and it sucks. Point -: always give it to load after use because it does not work on sector
Lifespan: between 3 and 4 years max (I utise 2x / week beard and hair) which is much - much as the hairdresser. this is my 3rd I buy.
