Customers find the rotary tool to be a quality, versatile tool that works like a champ and is as powerful as the corded version. The battery life and durability receive mixed reviews – while some say it holds up well over time, others report the battery doesn’t last and the tool only lasted 6 months. The size is problematic as the collet is too small for bits, and opinions on weight are divided between those who find it not too heavy and those who consider it too heavy.
