I've got four of these - 2 are still in good condition, but the other two are coming apart at the edges - the corner strip is too weak for the job.
I definitely wouldn't recommend them.
I've got an old black plastic Adda case which I've had longer, and is still is fine fettle.
I've also got a 100 count Swanflight, which is near indestructible, but isn't comfortable to carry due to the positioning of the handle (they position them centrally, which means they are slightly off centre when operated).
