In the description herein is a maximum online weight of 120 kg. In the manual, the maximum credit line is of 100 kg !! So if you have to rely on this information, you have possibly a device which is potentially unusable for a (or the risk that goes with broken use). Otherwise, I could easily build the device alone in 1,5-2h. After 1 week of use, I think it's quite good for the price. No frills - just train. Annoying noise I could not notice until now. In sum: A worthwhile purchase. But deduction for misinformation to maximum weight.
