I claimed this product and the company responded right away with a more than satisfactory manner. The problem with this product and in two things, we must put an elastic thumb or a longer queue, otherwise it is difficult to remove and it makes a little ill at training. Also at the inner there is a profile which leaves traces on the wrist for a while. But this product has great potential if we correct length or material to hang the thumb. The profile at the inner can decrease with time of use ....
