This treadmill screams value. It is hard to imagine that they can build a decent machine for $600 but the folks at Icon have done it. We still would caution to baby it and if you are a runner, forget it but we haven't seen a better value for the money. The Crosswalk handles are quite useless but that's the only part that is.
Walmart should sell a ton of these this year. If you are just a walker and take care of what you buy, this one has some opportunity. They really did their homework when they made this one. On the minus side, the heart rate grips on our test unit never worked correctly but I guess you can't have everything for $600.
