One of two warmer works fine

Reviewed in the United States on November 17, 2023

I ordered two of these warmers because of the added power port feature and a fair amount of good reviews. Up to a week ago, one of the warmers started shutting off at a whim and the light that lets you know it's on has gotten very dim. If there is any light on in the room where you're using it... you cannot tell if it's on.
So far, a mixed experience. Just glad my wife's is working fine. I wouldn't hear the end of it. lol

Controls coffee temperature perfectly. Be careful of combustible environment!!

For my second cup of coffee, I had to use less than a full cup because it would get cool. Now I use full cup and the temperature is perfect to last drop!!!
Unfortunately I placed the plate on a table with combustible material. In the evening I noticed smoke 🤔. Turns out papers and remote had slipped down on the plate and turned it on 😱. The papers were smoldering and the back of my TV remote was melted. If I hadn't been there a 🔥 would have occurred. Be very careful about the combustible materials anywhere near the hot plate!! I turn the power to the plate off if not in use 💡.

I dislike the fact that it has already quit working as far as keeping my coffee hot. I’m not sure if the heating element has quit working or what but I’m very disappointed.

Hot beverages to the last drop.

Very clean design. USB works properly. Coffee and Tea stay hot (not scalding or warm) to the end. No temp control or timer on this product. Looks as advertised.

Customer Service doesnt exist

Model: BlackVerified Purchase

Item works fine but customer service non existent. I tried to get registered for warranty and get a free cup they advise and it didn’t work when I tried to register on their website. I emailed customer service few days ago and still no answer. That’s the reason I give it 3 stars

Haven’t used the warmer yet. It appears we’ll designed for simple use,; sturdy.

Received a non-working unit.

Can’t even turn it on. It doesn’t respond to a tap of the button after plugging in.
