Spirit Esprit ET4 Treadmill Review
TREADMILL DOCTOR NOTE :
A model that gets kind of lost in the shuffle. We would either save some money and move down the line or upgrade to a model above. This is a no-brainer unless they give you one for the same price as an ET2.
The ET4 is kind of a throwaway model in the lineup. You would be better to upgrade to the ET6 for $200 more if you need the bigger walking area...you get a bigger motor to boot!
