Charged fast, easy to use. The clasps and zipper are smooth. I am not ordering from this seller again because I am not sure of the possible defects of the products that Im purchasing along with having to taking on the responsiblity of its return so that I can have it replaced or refunded. The wooly part hasnt pilled up too much or shed off for me, but I do yank off a scrap from time to time. Sa taille un peu trop grand So loud, so clear and full of BASS! Its straightforward to install. Mine finally gave out after a little over 3 years right around where you plug it into the phone jack. I don’t know if it was because my computer is not fully updated or if it needs a special type of sync/pairing procedure. So, I love these sandals on my feet.
