Good idea to keep the straps wrapped and transported. But I do not use the handle, such as the straps are highly scalable, with the weight and space, they end up "slip". It remains to find or make a bag to the right size.
Tested on 2 sessions only, a mixture of yoga, pilates, tai chi etc. For now, the carpet does not warp, does not take the marks at the supports, and holds up well enough on the bathroom floor (painted concrete). And compared to what I used before, although it protects from the cold concrete. It remains to see how it evolves over time, but so far I would say it is an excellent value for money for 1 to 2 hours per week. I am very happy with my purchase, I do not regret taking the time to look for THE good carpet, and I know I did envy around me.
