Work for a cleaning company that bought nearly all the Stihl 36 volt battery blowers in the stihl melbourne warehouse. The battery runs out in 10 minutes and takes 2 hours to charge. Stihl said run time was to be 25 minutes and charger was "fast" ( we didn't ask how fast though. Looks like stihl pulled a swifty on us). The power is nothing like the 4 stroke makita blower we were using before, even though stihl claim to be equivalent. RUBBISH
