Bought this primarily for Prime Video because nothing else work. Works well with Prime Video, Netflix and other built-in apps. Physically a bit larger than Chromecast and it comes with a HDMI extender which is handy in tight space at the back of the TV. Comes with a controller which is nice because I do not have to go looking for the mobile/tablet. It includes a USB power adapter, so it must be more power-hungry compare with Chromecast. The first time I connect it to one of the USB port on the TV, it complained about insufficient power. Luckily, the second USB port on my TV has just sufficient power to drive it, so, no need to plug in the USB power adapter. Overall, it is a great product. If I decide to stop my Prime Video subscription, I can still continue to use this for Netflix.
