I feel that the T5-5 tredmill is an increidible machine and very easy to use. I am on tredmills for many hours a week working on fitness. This is by far the best tredmill that I have ever been able to use. It is very easy to run on and I enjoy how quiet it is while trying to read, listen to music, or watch television. I would recommend this product to any person that is looking to purchase a tredmill. The price tag is high but there is a great warranty that goes along with it. If you are a gym looking to replace old tremills you should look no further. This machine will be sure to keep up with all of the competitors out there. If you take good care of the tredmill with proper lubing and cleaning it will last for a very long time. I have worked in a gym for over 7 years and this is the best tredmill that has come along. Easy to use and easy on the body which is what everyone looks for in a tredmill.
