Great product/No complaints or regrets
My wife and I have had a EFX 5.23 for almost two years. We use it often and have had no problems. We are very happy with the purchase. It is well-made and durable. It is easy to use and provides a good work out via its different programs and settings. It works well for people of varied height (i.e., from 5-3 to 6-3) and weight (i.e., 100 to 200 lbs). You can get a good workout, especially if you press yourself, but you won't have sore joints as you can get from running.
