I've owned a new Tunturi C60 Elliptical for 5 months now. I can say that in the 10 years I've been routinely using elliptical trainers, this is the worst example of poor workmanship and quality I've encountered.
Tunturi is always good at looks and presentation, but under the "stylish exterior" are the worst grade of parts and structure, and electronics China has to offer.
Bearings,shafts,and display on the Tunturi C60 have all failed within months of purchase. Replacement parts are also flawed and fail again within weeks.
If I have any good things to say about this machine or Tunturi ellipticals in general, I have forgotten them.
