Received this machine beginning of October 2011, regrettably by the end of December problems occured with the computer which prevent the machine from working. The company have advised i post the whole computer part of the glider to them (at my expense). At the moment they are currently trying to fix the problem. At nearly £500 this was a considered purchase, so i'm really trying to be optimistinc and hope this is not going to be a recuring problem; On a postive note, the glider itself, when working, is absolutely fantstic and really sturdy, in the same way a professional Gym quality machine is. It's just unfortunate i have encountered these problems just 12 weeks into ownership. Will keep you posted on how i get on but the company, so far, have been helpful.
