Battery lasts 90 minutes at speed 1, closer to 60 minutes at high speed, speed 6. Fully charged in about an hour. I can load and unload it from my car and it allows me to repair my mobile surfboard as if I never left the workshop. Brilliant!
Pros
Less dust - The micro-filtered dust container creates a cleaner working environment and the dust-proof on/off switch extends the life of the tool.
