Coffee Mug Warmer, Electric Beverage & Tea Cup Warmer Plate for Desk/Office/Home Use, Best Gift Idea Cup Warmer – LOOKISS

This warmer works well. It has two temperature settings. I start with high and when coffee gets down to middle cup switch to the lower setting which is still quite heated. Only thing is for it to work most efficiently you will need to use a flat bottom cup with no rim. I purchased a nice glass one on Amazon. If I'm going to drink coffee more quickly I still use a cup with a rim because I like my other cups too! Tip: cover your cup to hold in heat!

I was disappointed in this product. I barely keeps it's own surface warm and does nothing for the beverage. This is not a useful product - looks good works poorly.

I love the looks of this warmer. Very aesthetically pleasing, but... at best it keeps my coffee lukewarm on hot (The warmer has 2 settings and I have made sure the light is red which is supposed to be hot.) I have used several warmers, and I am sorry to say that this one does not do a very good job keeping my coffee hot.

I was so tired of my coffee always getting cold too fast so I ordered this warmer. My coffee was barely warm at all. I decided maybe if I put a lid over it, made no difference. Needless to say I'm very disappointed. I'm going to read reviews on others to see if they might do a better job.

It doesn’t work as well with the ceramic mugs.

Perfect temperature. You must be careful to not leave it where you might set something on it. Might burn. I would have preferred a toggle switch

This did not keep my beverage hot. Just warm. It was very good quality and I loved the red color but it just didn’t work for me on either setting. I tried different mugs but no luck. I returned it.

China and Corelle are fine. This probably a result of liability fears for burns if hot enough to work with a mug.Of course, I use a mug, so this explains the low (3) score. Otherwise the product is fine.
