I had a miniperceuse sector purchased at a discount coupon in a DIY store with lots of accessories. Given the difficulty of changing accessories, their lack of quality and maintaining them I had given up the idea to use it. I ordered this Dremel. Certainly it is (much) more expensive and only 15 tools counting the key but an apparent solidity rassurante.Le all comes in a kind of canvas bag, zip closure pocket on the side. It is regrettable that there is no support strap. The drill, the handle and the bag of accessories in bulk and settle at the bottom when you lift the bag by the handle. Damage The handle is handy to rest during precision work. It is easier to handle because of battery and can vary the speed of rotation of 5,000 to 30,000 rev / min. I will use it with more pleasure than the old. As the diameters of tools (2 mm) are the same, I'll keep the old strongest and most useful accessories and turn the old. One small complaint for the Dremel: charger for fast charging 1 h, which is the current trend. Yes, it is to always have a battery ready but no it is not good for the life of the battery. It emphasizes convenience and availability at the expense of life.
