Technically, I am, but since I opened it to try to fix it, I no longer have the warranty.
And honestly, it was partly my fault, as the button broke because I’ve dropped it (still, only from less than 1m). But because of that, I doubt I can get an exchange.
(I have to confess on the other side that the first one was completly my fault, as I had really badly damaged it).
It’s annoying, but aside from that I’ve been quite pleased by the player.
I’ve commanded another one for 36€, with a protective silicon gear this time, and I’ll try to be more careful in the future.
I’ll also try to fix my old one later, and post here if I can fix it.
Anyway, thx all for the feedback. 
At least I was able to try to fix it (and learned that glue and electric connection are bad combo, haha, costly lesson though).
