Purchased a 505 CST and its such a massive upgrade from my previous treadmill. Also customer support, especially from Josh has been impeccable keeping me updated throughout the ordering, financing & delivery process. Treadmill was delivered in two days into the room of my choice (furthest back in house), and self assembled in 2 hours with my son. Using iFIT now has taken training to a new level in terms of enjoyment, and I find it really motivational (I project from phone to bigger TV screen). I Hope to buy another fitness machine from them in a few months to compliment the treadmill.
