Precor EFX 5.21 i Elliptical Review
treadmill Doctor Note :
This Precor model doesn't make a lot of sense from a consumer point of view.
The 5.21i is a step up from the 5.17i, but if you are spending this much money go ahead and buy the 5.23. You get pulse grips, better incline ramp range and more user friendly features. If you can afford the 5.21i you can certainly afford the 5.23. Do yourself a favor and don't go around wishing that you had bought the better unit.
