For the money and the person who just wants to walk for fitness, this is a decent treadmill. It has manually adjustable incline, tracks speed, time walked, calories, fat calories, and distance. It goes to 5.6 mph. It also folds to save space, important in our small home.
If you're a "jock" or big-time runner, you may not like it. Otherwise, I've loved mine and actually prefer it to the ones I've used at the local Senior Center.
Check and compare Treadmills here before you buy any.
Check my pricing, ongoing promotions, manufacturer, mark and model, etc then make a decision.
