Only top, by just over 3 months a flop

In the beginning we were thrilled with this elliptical machine, there were no problems with the building still in use.
After about 3 months of use (only every 2 days for a total of about 1 hour) there was a huge imbalance, indicated by a vociferous jerking. Unfortunately, you could feel this also bucking while exercising in the joints. Since about Amazon no complaint was possible, we turned to Christopeit, but absolutely did not react.
According to conservative "Work trials", it was found that the mother, with the axis of the flywheel is secured (factory!), Readily dissolves. Now we have the right tool permanently deposited in addition to the coach (to tighten the nut again before every workout). How long this will go well, time will tell.
Precisely for this manufacturer I also at this price expected much better quality or at least customer service. Good thing there are other well-known manufacturers!

Addendum: A strong "screw adhesive" har really helped. Squeaks and creaks now it for use after a 5 minute -and not exactly quiet. The purchase was definitely a letdown. The only conclusion: Never Christopeit!
