Good points: More than sufficient motor for the treadbelt it has to power A fair number of built in workout apps Bad points: MSRP of is ridiculously high Warranty slightly better than the Performance 400 and 600 but nothing to brag about Comments: The Proform Performance 900 is a slightly superior treadmill to the Proform Performance 400 and 600. The upgrades include a slightly longer parts warranty, a much better motor, slightly longer treadbelt and more built in workout programs. It shares the same problems as its little brothers in that it doesn’t come with the iFit Live modules, it only supports it. A lackluster warranty of 3 years parts and 1 year labor is acceptable but not impressive if you can get this treadmill for which is what we expect it to sell for at some point based on its specs. Please don’t buy at the because it’s a blatant lame deal.
