When Amazon first showed off its redesigned Fire TV OS at CES, we were impressed. It’s faster, better organized, and feels similar to Google’s top-notch TV interface. The update is now finally rolling out to the Amazon Fire TV Stick 4K Plus, making it an even better buy now that it’s on sale for $29.99 ($20 off) at Amazon, Best Buy, and Target — $5 shy of its best price to date. If you want something cheaper and don’t mind waiting for the update to arrive, the Amazon Fire TV Stick 4K Select is also on sale at Amazon, Best Buy, and Target, for $19.99 ($20 off), which is $2 more than its all-time low price.
