This treadmill series is in my opinion one of the good brands you can find on the market. I have tried a few to say the least, but this is worth a shot. Its not that expensive as the rest and you can have this in your room or basement to use at any given time which is great for people that have a hectic work and personal life this works well. Performance On the Performance side this brand holds up its really easy to use and the digital menu on the front is easy to understand. Comfort This treadmill feels very light on your feet doesn't make too much noise and glides with ease as your using it to get your all in one cardio workout going. Ease of Use This machine is really easy to use my mom of 52 is not too heavy on tech savy and she knows how to program and use it to the best of her ability its straight forward. Durability This is back with a 5 year warranty i feel this brand if kept well can last you for quiet sometime. Design The design is pretty good i must say easy to use and understand and adjust to your speed and interval is great.
