I bought this ball there is six months and she very well despite 2-3 hours daily and intensive use by 3-4 people in the first month. It supports 120 kilos without problems and even if it is now well struck, it has not pierced. I have not used it for a month and it hardly needed to be plumped. I highly recommend if you plan to use it often, or if you have friends / roommates / children at risk of seeing and playing with. The inflator is a little damaged but still quite usable. In my memory the delivery was fast one week-10 days. The bill is in German, but there are many instructions in French. I highly recommend this purchase!
