Bought this for an older Samsung 55" Smart TV that had the old wireless LAN USB plug in that I could not upgrade. I could care less about the Alexa option as I don't personally trust the security, privacy and eavesdropping capabilities of any smart assistant products on the market today. As for streaming Amazon Prime Video, Netflix and Crave TV in HD it does exactly that, and really well. I don't use it for surfing the internet or using Youtube so I have no opinion on that function. The remote also works well as it can control my sound bar too. The initial set up wasn't that bad either. Using the wireless option, I have not experienced it cutting out as others have mentioned before, perhaps Amazon has worked out those bugs. I have been using this for a couple of weeks now. So far, so good.
