Proline Floprene Padded Forearm Support, Small

i boutgh size S; it's very tight and no stretch although the quality of the materials is ok. I wanted to return and subsitute with size M, but the seller is not responding at all, completely ignoring the request. Therefore only 1 star. My advice, good luck in choosing the right size, otherwise you'll sit on an product that you can't use!!! Very disappoiting and stay away from this seller.
