I've owned this tool for almost one year and use it five days per week in my welding/metal fabrication business. The performance of the tool excellent, it really removes metal with a 9" hardwheel. The problem is the trigger. I'm predisposed to like german tools, especially the ergonomics. The ergonomic design of the trigger/handle on this tool is poor. At first I thought I'd get used to the way you have to pull back and squeeze the trigger but I haven't. My hand is not small (medium sized glove is tight) but the handle/trigger together are too big and my hand is never comfortable. Bosch got it wrong on this tool.
