Amazon Fire TV Stick 4K Max for $33 ($27 off): Amazon's most powerful dongle supports 4K streaming with Dolby Vision, Wi-Fi 6E and live picture-in-picture mode so you can see security camera feeds directly on your TV as you're watching a show or movie. In addition to being a solid streamer, it also makes a good retro gaming device.
