Check every brand before you buy it, and if Icon Fitness is behind it, it's a good rule of thumb to just avoid it and keep shopping. Sure, there are a few exceptions, but in my estimation, just staying away from them altogether is the way to go.
The truth is, buying treadmills can be expensive, and you obviously want to save money. However, don't buy a machine just because it's inexpensive. What constitutes a cheap machine?
Anything that retails for less than five hundred dollars for a new model. Don't even both with cheap treadmills under this price, as it will simply be more trouble than it's worth.
If you've read my reviews of Proform, you know that cheap treadmills can certainly end up costing you more in the long run than expensive models, due to all the problems you will likely experience. Is Horizon the same?
