First of all this thing requires ifit account and a fairly good internet connection. Ifit is buggy, expensive and destroys the whole experience of mechanically sound treadmill. E.q. You can't create your programs without ifit. You have to have multiple ifit accounts if you want more than one person to use it. If your internet connection drops this thing freezes. The software crashes. It is not possible to setup the simplest run without ifit. E.g. setting up distance or time run, not to mention something like interval training. Ifit wants to know every single details about you, your family and your dog and agree to whatever nonsense t&c they come up with. Actually I made unfair comment about t&c cause i haven't managed to read all these nonsense - I would have to spend more time on reading than running. Verdict well build treadmill with absolutely rubbish software.
