The product is fully compliant to the specification and is immediately recognized by my TV Samsung Smart TV. Very handy for foreclosures in searches of Samsung apps. Before, it was just a horror with simple remote control. From a very compact size, this keyboard is still very easy to use. This is a rechargeable Li-ion battery (supplied with) that takes place in the device. Only downside: as many accessories coming from abroad, the keyboard is QWERTY. It is this aspect that made me hesitate between 4 and 5 stars. But we made it and the product necessarily still deserves its rating EXCELLENT.
