UCQ8OJIA should take off $11 on the black option. If you're using the Amazon app you might be missing the step of tapping on the arrow that appears in the promo code box to apply the code (before tapping the Continue button).

Amazon 90 day price history shows $9.99 as the lowest it went back in January for a couple of weeks. Now, with the promo code UCQ8OJIA, $9+tax is a decent price. I got my set delivered yesterday and they work well enough that I went back and used my wife's login and bought another set with the same coupon code just now and it still worked nod. The magnetic backs of the devices allow you to stick two together allowing wrap-around heating. Two sets will give me wrap-around heating for my two hands Big Grin.

Well I bought another brand for $6 and is pretty good. But if you think this is a good price, good for you. I'm not here arguing, I'm just letting people know that they might find cheaper. That's it

False advertising, they are not orange like in the pictures. and I see no evidence it has an AI chip that knows what I want.

Ok, but nothing is stopping you from charging these with your own C/C cable. Yes, it's not ideal since you cant charge both at the same time with their provided A/dual-C cable, but i think a Y-splitter USB-C cable would be dangerous albeit amusing

I have the brand name of these warmers (Ocoopa) and charging them with a C/C cable does NOT work. Which C/C cable are you using?

I've tried several brands of USB C-USB C cables along with several brands of power adapters. Upon researching this problem, I found out that these electric warmers lack the resistors needed to complete the connection handshake. Therefore you need to use a "dumb" A-to-C charging cable.
