As part of our exodus from cable, we bought the Roku stick. I like the fact that it has a remote, as I do not walk my house with a phone. However, if you prefer to use your phone as a remote, it IS nice to have option to download the Roku app. There does seem to be a delay once I turn my tv on. I wasn't sure if it was working or if I needed to press other buttons. If there are instructions, there weren't any I could find, so I had to figure it out via trial and error. Otherwise, I have to admit that it's a pretty nifty product.
Got my stick as a gift...easy peasy to install and set up. Interface is intuitive and simple to use. Picture was sharper and clearer than my old Roku. Plan to get another one for second TV. Do it!
