The mat is easy to assemble, even if the documentation is in English, it is not a barrier. the carpet is silent and settings are simple. You can not adjust the angle of the carpet, and the bar to keep a bit low (I measure 1.65m and I can not stand right while holding me). Despite these drawbacks, it is perfect for keeping fit (I use 30 minutes a day), and it takes very little space. Also, I enjoyed very very effective security system!
