First be aware it has to have an outside power source. If you have a USB on your TV it can power from that with a little short USB cord. Secondly, be aware it has a slow processor and slow boot up. When you turn the TV on it takes what seems forever (maybe a minute) for it to boot up. This is likely more of an issue for you if you have had a Roku 3 before which is lightning fast.(I have several Roku 3's)
I bought this about two months ago. This is the third Roku I have purchased. The remote for this device does not have the same range as my other Roku devices.
I bought this about a month ago and I have been delighted every since. Even the technician that helped me connect to my Wi-Fi said he wished he had one! I love it and it has become my new best friend. ha ha
I am thoroughly satisfied with my Roku Streaming Stick. The installation/setup was easy, and I was selecting channels and watching content within minutes. You have to be a bit patient when you first switch your input to the Roku from another source, but it's not bad. I like to use my computer to research and select channels so they're available the next time I use the Roku. I tried Chromecast first, and the lag was so great I couldn't use it. The Roku has none of the issues I had with that other device. Great product!
