Bests & Worsts Reviews from Amazon

First of all I'd like to say that I have been using Dremel rotary tools for many years. I have enjoyed using this tool and had always found it to be reliable. Then, I bought the Dremel 4000 and the flex shaft, of which I had used the flex shaft many times in the past and always had it connected. The first day the flex shaft snapped, then the Dremel stopped working. I "burned it in" as they say by following the directions and running the Dremel 4000 at full rpms for 5 minutes. Having thought that I MUST have done something wrong, it is Dremel after all, I bought a second 4000 and another flex shaft. I burned the dremel in, and it stopped working as well. I went to the Dremel site, and low and behold NUMEROUS complaints abound on their message board about this very thing. Needless to say I see no point in buying another 4000 as they simply are not what they once were. The first dremel I ever purchased was in 1991 and it was a great tool that lasted through everything that I needed it for without fail. With the 4000 I simply feel cheated and cannot understand why Dremel hasn't addressed these problems in their rotary tool and stopped selling them. It's not like I abuse my tools, I use them for what they are intended to be used for. And even treating the second 4000 with kid gloves it still stopped working. Not once, but twice. I can even see getting a lemon occasionally but having purchased 2, and then reading the problems others are having on Dremels own message boards, I have decided to go with another product. The Dremel 4000 is a waste of money unless they address the problem of these things breaking down repeatedly. While I love the functionality of the Dremel and all the various attachments that they provide for their customers it simpy isn't a good investment. I hope they meet the challenge of re-engineering this tool. I miss it in my shop.
