After spending a long time to choose the carpet MarcheAbout suit me, I bought this one last week. Fast delivery by carrier (only downside, luckily I was there as they do not prevent the day of delivery); the driver has placed in the room where I had anticipated, very helpful. Of course, I wanted to try it once: - Easy installation, can not be simpler - For use, it is best to understand English, but it is well explained Finally, this device is perfect for me (30 min per day) For those who do not understand English: after installation is easy: -Plug, turn on the switch, issue a "beep", get on the carpet, put the emergency block and attach it to his belt, position the feet - press the red button (on: off) it there is a countdown from March to January and carpet démarrre speed (speed) 1 - If you press the MODE button you can scroll speed = speed - time = time elapsed - dist = distance --cal calories = You can increase or decrease the speed by pressing + or speed speed - If, on startup, you press the MODE button and not ON, the speed increases automatically (at least on my machine), I would not recommend it for débutants.J'espère may aider-
