Lifespan TR4000i Treadmill Review
TREADMILL DOCTOR NOTE :
This is not the best effort that Lifespan has ever put on the market. You are either better off in the upper or lower end of Lifespan's lineup.
This one is like the missing child in the Lifespan lineup. Great features but you can get their full AC unit for only $200 more. Well worth paying the extra for the full AC unit. To be frank, we are surprised that Lifespan still offers this machine. The TR5000i offers so much more for the money that the TR4000i doesn't make sense. When you compare this $1,799 unit with what else is on the market from Sole and NordicTrack it gets damn near impossible to justify the Lifespan.
