I have two of these. The one with date code 0915 has been in use in my office as a mug warmer and, later in the day, as a coaster for cold drinks. I really liked having something to keep my coffee warm in the mornings.
Recently I came into the office in the morning to a strong burning electrical smell.

I was sold by the fact that this collection was hand-made in the US. The design is lovely, the plates themselves are very nice but these items are made in China, which for me detracts from the the whole idea of buying local, supporting an artist and enjoying something hand made.

I received this Mug Warmer which I ordered from Amazon and it was in perfect condition, clean, nothing seemed to be wrong. I first used it at my workplace and in the first day it was just perfect and I was talking to my colleagues about it. They very much liked how it looked.
Coffee Joulies, Set of 5

I recently purchased a set from Coffee Joulies, and had really high hopes. PCM technology has vastly improved home insulation and other areas, and I was excited to have this technology work for my morning coffee. To start off, I read all the directions and used them as directed, and I never add cream.

I wanted to love the mugs. They are nearly identical to a pair purchased at a big-box retailer and we were looking for more of them. However, it appears that we are only able to love 8 of the 12 purchased. The 4 mugs representing the the balance of the two orders cracked.

What a disappointment. I got this for my adult son, who was, at first, thrilled with it. Pour in the hot water, make the Tardis sound and watch it disappear and reappear on the other side of the mug. Do it only once, never again….

I searched high and low for a mug like this that was NOT made in China. I posted a question in the Q&A section, and another buyer told me it was made in the USA. Every other mug I looked at was made in China, so I went ahead and ordered this one.

These are a bit thin. They look great, great size, but whoa I’m kind of afraid to wash them. We’ll see how they hold up.
*edit/update these guys have been holding up well and we use them everyday. So far good in the dishwasher. I just honestly can not tell of they are actually glass?? They really seem like plastic.

The cup is great but not sure why people sell it online for so much if they are only 18 something in stores

It is cheap; that may be its only positive feature. I went by the so many positive reviews, but in the end, I was misled. I don’t know why people liked it so much. There were three issues that I encountered. 1) It is not powerful enough. Other similar products have more power. This affects how warm it will keep your beverage.

Finally, I found this "New-Commercial-Grade" stainless steel cup that would accept my handheld blender head. I meanwhile used this cup no more then 5 times for that purpose, with great satisfaction. However, "Update International" (what’s in a name?

I ordered a set of 2 of this same brand back in 2011 and they are very well made and durable. Solid espresso cups. Still have them, still in perfect condition. I ordered this 4 pack thinking they’d be the same. Nope, no, not, nada, not even close.

If I had wanted a crudely painted animal made of ceramic, I would just rummage through my storage bins and find something my children made in elementary school. And Why are the dolphins eyes red? Probably because he tried scratching them out after seeing how terribly they painted him.

These cups are fine to use and great for coffee but one of the four cups failed less than 6 months from purchase. When contacted for a replacement or refund a person named Andre answered by email that “glass is not covered in the warranty”.

On the 4th time I used this mug I tried to make tea. I poured hot water, not even boiling just hot, against a teabag into this mug and it shattered into three pieces. I thought this mug was capable of holding hot drinks as well as cold but I guess not. It’s beautiful but I dont reccomend spending the money on a mug that won’t last a week.

This is a "mug lukewarmer", NOT a mug warmer. I would return it, but, unfortunately I tossed the packaging materials. I trusted the (fake) reviews on it. Glad I only ordered one, to check it out, instead of the three I needed.

I ordered the panda mug, but what I got instead was the cat mug painted like a panda. Disappointed!

the warmer works best with the supplied FLAT bottom mug. Unfortunately the mug I received came with a “rust type looking ring” on the inside of the mug. I thought it was cosmetic, so I tried it…….not the case, the taste of my drink was off. If you don’t have a flat bottom mug, I would not buy this.

I see the one- and two-star ratings far outweigh the five-star ratings, and for good reason.
I saw these on “Shark Tank” and thought this was THE thing I needed. I was tired of my tea being too hot for far too long in my well-insulated mug, and then having to drink it up fast when it was at a nice, warm drinkable temperature before it…
