Presenter remote control works fine so far. It's small and light, perfect to take with you anywhere with ease. It was very easy to connect to my Mac Book. However, the bright red light doesn't work on the TV screen, so I can't use it in most of my classes. Another question is that since you have different products in the same addon I got confused with the reviews and found that the presenter does not require batteries. but it is so. There's also a small display for checking the battery level, but it's not very practical.
