well, after reading that many positive reviews, I decided to buy one.
delivery and assembly were flawless.
There are some strange things about this piece of equipment, however.
1. all the labels on the equipment are in German. Not a problem for me, because I am a German living in the States. Must be strange for locals, though.
2. the pulse meter is completely inaccurate. I was rowing like mad to get my pulse into my aerobic zone (130). Once I was exhausted and double-checked with my chest-strap based other pulse-meter, I was already beyond 150, when the Kettler thing still showed only 110. If you don't want to kill yourself, don't use the built-in pulse meter.
Besides, I hate having a cable dangling at my ear while rowing.
3. at the beginning of my 2nd training session, when I tried to fix my shoes with the 2 tapes which were provided for this purpose, one of the plastic rings broke. It is made of such a cheap material, it cannot last for long.
4. I can't prove it, but I have the strong impression that I have to apply different levels of power on the right vs. the left handle, no matter to what "level" I set it. I always have the feeling, that I have to pull a lot harder on the right side than the left. That does not feel good.
5. it is not as quiet as I expected it to be. The rowing motion is ok. It is the sliding seat which I am worried about. So far, my wife doesn't complain when I use it at 6am in the morning. Still, I think, this is an area of potential improvement.
Would I recommend it to a friend? no.
At this price range, I would not have expected those kind of flaws.
