I am on the whole satisfied with the product and train diligently already. From a processing perspective, it's solid, but not premium class. Are certainly much better equipment, but also to the higher price. From the square it's okay. And I wonder if the round and red and silver box would forward the size must fail. To point noise reduction I have also made me some thoughts and am even intervened. First of all, roughly speaking, if one operates in the hobby room, the noise should not bother. But if you want in the living room make sport while reducing the noise (the size of the noise really is not and does not come from the box front but 90% of the rail and the rollers on which you sit) then you can really do something. I have been on the top of the rail where the seat is placed 2 layers Gorilla Tape (also here to buy from Amazon) it stuck. In each case a continuous strip (ie really a long strip, not a patchwork, because then jolt it sounds) just stick on top of the rail and then another about it is a little thicker and damits the sound is absorbed. You can if would like to make a third strip on it, but closing is somewhere then it is because no longer fit through the rollers under the seat. Before that, I'd end up the rail wegschrauben the nub and the seat move, so you can stick a continuous strip on the rail. Obs makes sense under the side of the rail or under it (where there are also roles) to glue I doubt. I habs times looked more closely, the wheels on the bottom of the track do not touch the rail. The weight comes indeed from above and pushes more to the top of the rail, and hardly at the sides. The result in any case a very massive noise reduction. Since the manufacturer would also themselves can come on it and so can mitreinlegen a slightly thicker tape. I'm not an engineer but only hobbyists, but for me the matter was clear that there can do what, after I draufgestarrt intense 5 minutes. As it stands now, it purrs like a kitten anyway. Here is a picture what it looks like: [...]
