Welcome to Day 3 of CNET's 10 Days of Deals! These are items I consider to be all-around awesome, with discounts you won't find anywhere else.

What's worse: A bed that's too cold or a bed that's too hot? Trick question. They're both terrible, both a threat to getting a good night's sleep. And make no mistake, you're not getting as much sleep as you should be.

Wouldn't it be nice if your bed had its own thermostat, a way to warm or cool it to exactly your preferred temperature? That's the BedJet in a nutshell. If it sounds familiar, perhaps you recall seeing it on Shark Tank?

The Sharks didn't offer its inventors a deal, in part due to the $499 price tag. That's steep, no question, but the current-generation model is now on sale for $339. And today only, CNET readers can get the BedJet v2 for $274.59 with promo code CHEAPJET.

The BedJet is exactly what it sounds like: A climate-control system that blows warm or cool air into your bedding. You use the companion app to set the temperature, timer, flow rate and so on, though there's also a wireless remote for quick access to settings like power and temperature.

This is a single-zone system that works with any size bed. I haven't tried a BedJet myself, but the 640 user reviews at Amazon average out to an impressive 4.5 stars.

It's worth noting that there's a v3 version of the BedJet currently available for preorder on Indiegogo, with delivery expected in December. But as a general rule I avoid Indiegogo purchases, because you're a "backer" and not a customer -- and therefore enjoy fewer rights if something goes awry.

Indeed, when you buy the BedJet v2 directly, you get a 60-day money-back guarantee, with free return shipping and no restocking fee. Are those same terms afforded to the Indiegogo option? I don't know. Shipping costs extra, and the return options aren't indicated anywhere.

I'd say if you're in the market for a better night's sleep, the v2 is definitely worth a look -- especially at this price.
