I bought the package for myself, without really knowing what it was. It was actually more a coincidence that I could find this role for me, because the other part was sold out, which I was looking for. The name Rocket and Rocket spoke to me incredibly, because I have a fable for fast objects, and wanted to see if I can use it for me.Surprisingly, I found the good relationship between the purchase price and the actual performance behind it. One is wondering, of course, that the purchase price is relatively high in the purchase and is amazed that you have to spend a simple accessory so much money. But why the device is so expensive, in relation to other devices, is shown on closer inspection but quite fast: one has the possibility to move at such a lightning speed that it is quite the same. While you, as an experienced customer, often get into a sweat and have fears, for example, because the parts get tangled up or because of the speed, it is also very error-prone, one establishes in the operation itself that it is easy to handle The But a small disadvantage has the object, it is very difficult for my terms and leads to rapid fatigue. But if one does not take the flaw once in the eye, one can actually be very satisfied with it. What you have to emphasize on this device is the extremely fast and powerful cord feed. It is promised in the advertising that you find a speed that you have never seen and you think that it was first a real exaggeration. At a second glance, however, it is noticeable that not only the speed is excellent, but also that I can also see the train behind it very much. Since you have for the money a real power package for itself, which weighs a lot and is therefore heavier in the hand, but then on the second train really makes up for this effort by the power behind it.
