I've been using these the last few years now and they've held up very well. One minor irritation is the machine hole cut at the bottom of one of them, which is to allow the speaker pole into the speaker through the cover itself, wasn't cut exactly right and so the material can get stuck in the speaker socket if you don't line it up perfectly. This is difficult and an annoyance. When it gets stuck, there is no way one person alone can remove the speaker as it wedges. I then have to drop the speaker to the ground, with stand, and lay them both down horizontally with speaker still attached. I then have to spend a few minutes trying to prize the speaker form the pole! Te obvious solution would be for me to cut the hole bigger with a scissors but I don;t want to affect the integrity of the case itself. I would buy them again however, as they are all in all, a clever design.
