For the size and price, and its water resistant design, this is a great way to keep hummingbird feeders liquid in winter - use gaffer tape to attach it, then wrap some bubble wrap under and around the feeder. For hot drinks I don't think it's hot enough, but it might help slow down the cooling.

Coffee mug outer diameter must be small for it to fit in this warmer.

Inutile. Ne vaut pas le prix. Ne chauffe pas assez pour garder qqchose de chaud - pas même une tasse de styromousse...

Il ne fonctionnait pas. Le produit a été remboursé mais je n'ai pas encore reçu mon relevé de carte pour affirmer que le remboursement a bien été fait.

Very disappointed with my purchase! The pad warms up the bottom of a regular mug and that’s about it. Doesn’t work for its intended purpose of keeping your beverage warm.
