Here's the story from the beginning, first the original review:
First of all I must say that the stepper has to accept a few kilos quite well helped me with my aspirations, yet had the benefit only of very short duration. As other reviewers have written, the device begins after a short time to squeal on, suggesting, however, be solved by greasing or with "Caramba" spray. Much worse, however, is that with regular use (about 30 minutes per day), the pulley, which is responsible for regulating the stroke of the stepper stage wear. I bought the stepper in February 2015. Now we have April and the guide pulley is broken. It is broken by the metal bush in the middle, thus the metal bushing holds no more, the game has become very large, thus the stroke of the steps the unit is only minimal and therefore unusable. Very bad!
Update 28.04 .: After the customer had made a comment, I have received e-mail please contact the manufacturer and described the problem, and also sent photos of the defective part. Very positive: Even during the morning I received a call regarding the settlement of the warranty. Very friendly and competent. The course improved my impression!
Update 08.05 .: The friendly and competent customer service of occurrence of the Ultra Sports has surprised me very positively. In the vote for the settlement of the guarantee to receive a replacement device was assured. This has been delivered by parcel service yesterday. Visually, it looks just like the first, the noise that was present at the first device almost from the beginning can not be determined in the first test. So I hope that now everything has changed for the better!
