For a $100 more you get a much better machine from Lifefitness!
Solid linkage system
Paying a lot more for a few extra features
Overall Rating :
Like most companies Lifefitness will knock you brains (i.e. wallet) out for a heart rate control system. Don’t fall for it. If you want Lifefitness buy the X9i. It is essentially the commercial elliptical for your home. If you cant afford it . . . buy another brand!
