3 weeks ago I received my first Dremel 4000. Well packed in a very sturdy case came to my Dremel. Since I already use the Dremel Hobby battery a long time, I knew me from the operation and must say: HERE LIES POWER OF IT !!! With 65 accessories, which were obtained in delivery - can accomplish all kinds. However, I noticed that an additional part was missing - Speed Click / quick-release attachment part. I wrote to the manufacturer and informed with. After a few days I received the missing part. I thought that was very accommodating. Unfortunately, there was another problem. After a few days of use Dremels, I had difficulties turn the Dremel. Time he went on without any problems, then again not make a sound. After I contacted Amazon 3 days ago, I received a new yesterday. The delivery of the goods was as always very very quickly.
Now I hope that this model does not do so quickly limp because my conclusion:
Apart from the recent "problems", this device is only to be recommended. I do not want to give it back.
