Pocket wireless Keyboard is the new revolution. Folding Bluetooth keyboards solve a problem with virtually every tablet and smartphone out there: Their on-screen keyboards all kind of suck. Some tablets are large enough to provide users with a full-sized keyboard, but a lack of tactile feedback and key travel still make for a crummy typing experience over time. And while tablet keyboard covers or cases exist, many of them work only with a specific model, and can be prohibitively expensive.A folding Bluetooth keyboard can be used with multiple devices and can be a different size than the tablet or smartphone they’re paired with. And when you’re finished typing, you can fold them up into a very small and easily stowed item.
