In general, a great thing. I wanted to buy a Dremel in general (I have to cut, drill, grind small crafts), but the reviews alerted me (reliability is lame). I bought a proxon - a wonderful device.
Some pros:
A good machine, the speed does not sag, it is convenient to work.
Different cons:
Warming up. It is difficult to call this a disadvantage, after all, the speed is high, but it worked for 20 minutes and the machine is noticeably warm, closer to hot.See full review
