It is not only sturdy but seems to be made very well. I have been using this mouse for about a year, Ill say that its a solid mouse for the most part. My daughter didn?t have these slippers not even 24 hours. I tightened these up to the max and they fit like a glove. Et ipx7 (pour toute météo) All in all I would definitely recommend these headphones. Beautiful color too. Not comfortable for my daughter?s heal. So much smaller than you?d think ??. and still keep my feet warm.
