The item works as it should. No problem syncing with my TV box. All functions work well. Only 4 stars because the backlit colours are difficult to access. FN + F2 will allow me to access 3 of the colours (red, green and blue). To access other colours you have to swipe the touch pad with your 2 fingers. This is somewhat hit or miss in that it can take several swipes to change the colour. On my keypad I was able to access 6 colours in total. Really though, can't complain about that but it is a bit of a pain when using the swipe feature. That's why only 4 stars. I would definitely recommend this item.
