Got the Bosch 41LI and I use it for some of my clients. It's the old shape and has been hammered.
Only problem I've had was the safety clip that cuts the circuit so I simply bypassed it.
It's been good but lacks power and clogs easy. Wheels are bald now but it's lasted 5 years of me throwing it about.
Next one though will be one of the Viking Batt mowers.
