I purchased this treadmill a year ago. While the extra features are nice like the fan, the so called impact reduction does NOT exist on this thing. I also belong to a gym & I do 2 miles on that one with no problems or aches/pains when finished, on the 450 I always, always, always am achy & have pains from the hips down. My 17 year old daughter also uses it and complains about the same issue -- spine, hip, knee and foot pain.
My advice? Save up for a better one! Your joints will thank you later! There's that old saying: "You get what you pay for" -- it's completely true.
Check and compare Treadmills here before you buy any.
Check my pricing, ongoing promotions, manufacturer, mark and model, etc then make a decision.
