This streaming stick is a good deal. There is barely any lag time and the picture resolution is good. it does lack 4K support. My only complaint is the inability to turn the dongle off and the remote drains the battery fast. The other issue is the remote can become unresponsive. It requires me to remove both batteries and reinsert for the remote to work again.
Bought this to facilitate watching streaming content on an older "non-smart" TV. It works great, as well as making a variety of other content available. I have the stick with the remote which really makes it easy to switch sources.
I use it for Netflix. I have no idea what the other buttons are for and I don't use them because I don't want to get charged for something just for looking at it. I wished in your in instruction manual you would have told us how to use the other functions. I'm 70 years old and it was a little hard for me to understand ,but it works great on Netflix.
