Don't know anything about them. I took a look at their website. Their budget Horizon brand I don't think rates very well. I've seen that brand at Canadian Tire, which is probably not a good sign for robust fitness equipment.
My LifeFitness treadmill is 10 years old, and I bought it used, so I'm guessing it's at least 15 years old. But I don't use it much. Maybe 3-6 times a year, when the weather outside is really bad.
