I have purchased this product personally for my self and i m horribly happy to get it. I am using it since last 5 days and its working very perfectly. I have put on some weight and it is veryhelpful for me for jogging in morning. I am 78 kg and i m running on it with 10 speed without any problem. It s awesome product thanks durafit. It also doesnt make any noice and ruining pannel is also very smooth.
