I really cannot understand how this can be true. I've bought my speedstroke just a month ago. The quality is excellent. And there are no "washers holding the seat down". So there is no way that they could have worked their way through the seat. I am afraid that Jack_S is talking about a different company.
Anyway my personal opinion is the exact opposite. Quality is great. Service is great too. i bought mine over the internet. All my questions were answered the same day. The product arrived on time. Papework was fine too.
I have been using the ergometer 3-4 times per week since I bought it. I had an accident early on September, dislocating my shoulder while whitewater kayaking. Working out on the speedstroke helped me regain my strength fast, and I am now back on the water. Just got back from a 3 day whitewater kayaking on the Greek mountains. Without the speedstroke I woulld probably mish this paddling season.
I am glad that Virtua-Race is now available. This is one of the reasons I've chosen the speedstroke. I am sure this will help me keep on using my new ergometer once, as expected, I start getting board paddling at home.
