I bought 3 of these Gumdrop cases back in August 2020 for my iPad Air 2 at £12.99 each.
I fitted one and kept the others as spares but never needed the spare cases. I’ve now updated to a different iPad and have bought the correct Gumdrop case for that version and sold my Air 2 with the Gumdrop case still fitted.
These are awesome cases which I originally discovered when the airline that I was flying for used them as protection cases for their iPad eFBs (electronic flight bags). I can’t see myself ever using a different style of case as they’re so good, I can throw my iPad in my flight bag and never be concerned that it’s going to get damaged.
The same Gumdrop case for an Air 2 is listed by others at £18 plus postage here on eBay.
