The tool is well balanced and compact. I do roadside assistance and there hasn't been a single nut this tool couldn't crack. a while. Works well in heavy rain. My bits are rusty but the percussion gun is perfect as far as I can tell. I couldn't figure out the Bluetooth capabilities. I'm not sure what the benefits of the BT are. Everything you need to know is written on the tool. Not a big fan of LED light placement. I'm a fan of how to toggle it on and off. The light has more than decent transmission, but the place is subject to shadows. I like the anvil and bit socket design because it gives you so many adapter options. This will make the anvil slightly lighter. In my job, that wasn't a problem. The balance and compactness of this instrument is excellent. This is the BMW among cordless impact wrenches. German engineering. Probably made in China though. I like the speed switch. The anvil design and speed selector make this tool very versatile, allowing me to only remove the nuts I want.
