I bought a Horizon CST3.5 Treadmill in 2006. Now it’s broken. Horizon Fitness contracted his customer support to another company. That company charged me $99 upfront just for someone coming to my house to look at it. Then the guy who should come gave such hard time to make an appointment. He almost want to come to my house next year. I spent more than half hour for just set up an appointment with him. My money is already gone. Otherwise, I would rather to buy a new one instead of suffering from this guy. Don’t ever buy from this company again. Next could be you!

I’ve now had this treadmill for two years and put it thru all the paces and over 2,000 miles at speeds from 12MPH (full sprint) to 4MPH (walking) and all the inclines as well. I walk about 2-3 miles a week and run about 20 miles a week on it, at around 8MPH and I weigh 170. I use mostly the ‘manual’ process where I change incline/speed on the run…but also set up two custom workouts. I’ve only had to reset the mat twice (it eventually will slide to the side and start catching a bit) and also have only lubricated / cleaned once, though it’s due for another. That process was also relatively easy, but you need to dedicate a 1/2 hour. I can’t see spending >$1,000 on a treadmill!

We’ve had this treadmill for exactly 1 year and it gets regular use. It had been fine up to this point, but we had to have the belt and frame replaced last week – thank goodness for the warranty. The technician that repaired it said that this model has a very weak frame and cracks are common. Ours had cracked all the way from end to end! I suspect that part of the problem is my husband’s heavy running because I had never had any problems with it and I normally just walk or jog lightly. The belt also slips and rubs the sides sometimes. It’s a decent value for the money and great for walking or light jogging, but if you intend to use it for heavy running, invest in the more sturdy gym-quality ones.

For years, my husband told me we couldn’t own a treadmill because they are too expensive, tear up too easily, cost a lot to repair and we would never use it anyway. I persisted for 17 years and finally for our 17th anniversary, he told me I could get one! I researched treadmills on Consumer Reports website and found this one to be a best buy. We went to several stores and looked for one but the prices were all over the place. I searched online and found it on Amazon at one low price, no tax and no shipping. It was way less than anywhere else. In a week, I received a call from the shipper and a time was set for delivery. They were great and came on time, brought in into my home and I actually assembled it all by myself! It has worked perfectly. It’s easy to use, it’s quiet. I have used it at least 5 times a week since August and I have never felt better! I highly recommend this purchase!

THIS A GREAT TREADMILL. IT’S FAIRLY EASY TO ASSEMBLE AND IS EXTREMELY QUIET. THE BEST DEAL I COULD FIND FOR UNDER $800.
