When you use an iPhone media player or smart phone to watch video on a plane or train your stand needs an adjustable viewing angle to cope with the cramped space and to avoid reflections and grip to grip the tabletop and to grip the device. The Crabble is the only wallet-sized stand to offer an easily and continuously adjustable landscape viewing angle ranging from 45 to 90 degrees and with its rubber claws it is the only wallet-sized stand to give you that grip. Designed originally for the iPhone the Crabble is suitable for most largely symmetrical devices less than 16m thick and 65mm wide. To work in portrait format devices should be more than 50mm wide. (An iPhone 3G S is 12.3mm thick and 61mm wide.)
