The clock is ticking — you have less than 12 hours to snap up an Amazon Fire TV Stick, Fire TV Stick 4K, or Fire TV Recast on the cheap, as Prime Day draws to a close and takes the discounts on the cord-cutting devices with it when it goes.

To recap, Amazon has knocked $25 off the standard Amazon Fire TV Stick, dropping the price to just $15; $25 off the Fire TV Stick 4K, sending the price tumbling to an all-too-tempting $25; and $100 off the Fire TV Recast, plunging the price to $180.

But what do each of them do? Let’s take a look.

The Fire TV Stick is the most basic bit of kit in Amazon’s cord-cutting arsenal, offer one-click access to a slew of leading streaming services, including Amazon Prime Video and Netflix — but it’s streaming itself is capped at a Full HD resolution.

Pair the Fire TV Recast with a Fire TV Stick 4K as part of the Prime Day sale, and you’ll be saving a cool $125. That’s almost on par with how much a year’s worth of Netflix will run you, so you’re essentially getting it thrown in for free (in terms of raw savings).
