concerning the control and the merchant: BRAVO delivery made after 3 days about the product: very pleased, it corresponds to my expectations, ie a treadmill that allows me to exercise 30 minutes a day, so not a great athlete carpet! but you can adjust the intensity, see the time, etc. it is easily installed, the program also includes easily even if the user manual is in English. Only downside: the bar to keep a little low, resulting in a slightly bent position to walk but may be it is the case for all carpet a good deal for that just wants to move
