I have had this product for a week now and am in shelter-in-place mode during the coronavirus pandemic. I'm sharing this to provide some insight into the testing (or lack thereof) this product has had for me so far when asked for my opinion. Firstly, however, the product was delivered earlier than expected. It was nice. Second, the price was reasonable for what I wanted. Thirdly, the product itself looks like it is made out of durable, high-quality material. My AirPods fit easily and comfortably into the silicone case. The included carabiner came in handy once I clipped it to my jeans for portability, although I prefer to clip it to my backpack anyway. When opening/closing the AirPods case, there is no interference with the surrounding product. To be honest, I don't know if this product is needed to "protect" your case, but if you want to add some support to your AirPods case or want the option and convenience of case clipping, I highly recommend it.
