This small handheld keyboard is perfect for people who, like me, have a little trouble with the touch and have been trained in typing on QWERTY. I first tested my smartphone, but the screen is small and I do not feel at ease to write text. By cons, with my 10-inch tablet, it's great. It is easy to apairer: we wait for the blue LED flashes simultaneously pressing 2 keys. The instructions then announces a purple light story that I've seen on any of my devices both, but hey, the installation went smoothly without this famous light. Typing is pleasant, it just remains for me to identify how power certain punctuation or special characters, as I can anyway write with the touch needed. An online manual is available if difficulty. It is with my little laptop keyboard I am writing this review I am delighted that apparareil, very convenient for me.
