Hard glasses cases feel sturdy. However, I haven't used them long enough to know if they hold up or not. My only complaint is that a couple has sticky patches on the outside edges where the piece of plastic that holds the interior material to the case is. It tugs on fingers and doesn't seem to be prone to drying out.
