Looks very similar to the EVO iPad extender I bought from eBay UK for £3 and change. Amazing service: the jaw opening at the top wasn't wide enough to fit over my iPad Mini2 so the vendor produced a replacement to my specification, with an 8mm jaw opening - on Christmas Day! It now fits like a glove, holds the iPad securely and will do for me. My guy also ships to the US but that cost is disproportionate.These adapters should take care of most tablets! I Fabbed them up so I could use a lenono tablet and my Ipad Mini once the IOS app is done!
