An amazingly feature packed machine for $600. When you lift the hood, you realize where they took the costs out. Heart rate didn't work very well on our test unit.
Everything has its shortcomings but for $600, this is not a bad deal. You will be surprised how well everything fits together and the feel of the machine has that of ones costing much more. The problem arises if you really try to use it as a serious machine but we'll be happy to sell you parts if you want to use it that way.
