I’ve been using this treadmill daily for slow jogging at around 5 mph, and overall it’s been a good purchase. I’m about 200 lbs and it handles my workouts just fine, though I wouldn’t recommend it for heavier users or anyone planning on intense running. It’s definitely better suited for light to moderate use. For the price, it absolutely serves its purpose. The installation was straightforward—just follow the steps and you’ll be fine. My only real issue wasn’t with the treadmill itself but with the delivery. It arrived with a few broken parts, and I’m currently working with Best Buy to get that resolved. Once that’s sorted, I’ll be fully satisfied. Good product, just wish the delivery had been better.

I only use this treadmill for walking (at least 20 miles per week on an incline). It's great for that, but I don't know how it would be for running. It has automatically recalibrated the incline a few times over the last month, not sure why it keeps doing that. The thing I find strange is that it has no instructions on oiling the belt. The manual says to call customer service if you think the belt needs oiling. I bought this on sale for $100 off, so I'm very pleased with the price. My last treadmill was a higher end treadmill that lasted over 15 years of daily use (with me walking and my husband running). I don't use iFIT and am happy the treadmill works the way I want it to right out of the box.

I worked as an alarm technician for 30 years. I have been out of the field for over 3 years and work at a desk now. This was the best decision I have made for myself. I have been using this treadmill for about 3 weeks now. So far it’s been great. I power walk and do some running. My legs aren’t so stiff now.
