entirely suitable for my phone Archos 45 .Grève certainly a little but protects the thickness falls (lived). the valve downwardly does not hinder the use of such. only the clasp encroaches a (very) little about charging USB pin, finishing OK.j I'm not using the pen, my son uses it to sound as: there too impeccable.je have not yet installed protective films. Considering the price it is a nickel product.
