I'm planning to buy the Logitech K400 Plus for my Android TV. I've noticed 2 different models doing rounds on the shopping sites. There's the "K400 Plus" and the "K400 Plus TV". As per the Logitech website, the former model is mentioned. The latter model seems to be fake by the looks of it (no Logitech logo anywhere). Is it really a fake? I returned the latter assuming that it was. Or has there been changes to the original model?
