The protective case I've had for at least 5-6yrs, finally fell apart, so I needed a new one.. I chose this and thought it would work well, because it has a lock on the outside , so your top wouldn't be flipped up accidentally .. You also have to put an adhesive strip on top and bottom, to hold the case onto your AirPod case, but even when it's locked, the top keeps popping off!! I've already replaced the adhesive strip , on the top, but don't think it will last longer than the 1st one, which lasted less than 12hrs before coming off!! Going to have to return!!
