This is one of the major steps I have taken to improve my TV in my home.
This review is based on the fact I purchased by very first Firestick streaming device, I got the Firestick 4K Max, connected to my Asus RT-AX82U Wi-Fi 6 router, and the speed is fantastic! No lag, no pauses, freezing, like my other older box. What a huge difference! I’m very happy with my Firestick 4K Max device, it came with a HDMi extender, cable, charger, and 2 little booklets. There’s many other streaming devices out there, it depends on your needs and if you prefer an Apple iOS, or an Android based OS. I personally love both, they have their pros and cons, of course. Just be aware that you’ll be prompted to update the devices software prior to use, I had 2 updates to install before I started using it. Also, make sure your modem/router settings have the firmware updated, prior to connecting any device. Overall, I’m very satisfied with the performance, and how quick it is when flipping through.
That’s what I have experience from the Amazon fire TV stick.
