Color Changing Mug - Happy Face Mug 12 oz Fun Coffee Mugs Color Changing Coffee Mugs Tea and Coffee Mug Heat Changing Mugs

Just perfect! Love it!

I used the cup every day and am glad I bought it

The media could not be loaded.  I’ve used it for a while and it still holds up! The “battery” light is on both sides and it actually stays true to temperature! Cool!

Really nice and fun set! I ordered 2 sets and 1 single cup for myself and friends as a gift. It is really fun! !!! It's brings smile on faces of people right away ! And I kind of feel brighter as its light up and go from black to color and smiles.The reason I don't give it 5☆ is : #1 set of 3 I ordered for myself, and I ham glad it wasn't present! have defect on one of 3 cups, black glaze not smooth above one of the eyes, I am not going to exchange it just because I don't want to waist time with shipping anymore after all holidays! But it would be a problem if it was for someone I planing as a gift .#2 It's all looks really nice and fun ,but cup ( I think paint of the material ) have some chemical smell, not strong but I do notice it as I drinking my fun tea . So... I will continue to try them for next week or so ,making sure I don't get allergic reaction or something ( I am chemical sencetive! ) And I did washed it in warm water with soft soap before use , but smell didn't go .Again it's not strong, but give me some concerns about it.#3 not able use microwave or dishwasher, and I don't use either much myself but for many it could be very inconsistent.Over all ,for now ! I absolutely recommend this product! It is fun to have at home and with friends. Nice unique gift for friends and coworkers, not expensive, nice box for both set of 3 and single cup ,ready to be gifted. I liked this, make it easier, especially if many gifts!Delivery was fast, everything shipped inbabble wrap. As always with Amazon on time!If no problem with glaze on one of 7 cups I ordered I would give 5☆ But for now 4☆.Will wright update if something changes during use !

This is just a fun mug. Color changing battery is fun for conversation when having that first sip of coffee with the wife

The media could not be loaded.  Paint peeled off after less than two months of use. Had to toss it. It’s cute but it fades fast. Does not keep drink hot for long because it’s thin.

Es para un regalo, me parece bonito algo diferente.

I am a hairdresser, and I ordered this coffee cup to use at the salon. All my clients love it, and all my coworkers plus their clients love it as well lol. It changes to the yellow smiley face when I pour my coffee. There is a slight hint of the frowning face and eyes that shows through after the hot coffee is poured in, just because of the different shades of yellow, but it’s nothing that would stop me from using or buying it. A fun little non-important extra is that after the hot coffee is poured and it changes to the yellow smiley face, it will also show your fingerprints when you touch it. I recommend this cup :-)

These are gifts and very much Ed loved by the receiver. Colour change effect is perfect and changes back to original when cools. Awesome choice!

Love these mugs .Well worth the money will be buying more they so cute and different would definitely recommend

Estan bien pero como las laves en el lavavajillas durante mucho tiempo se despenga el dibujo exterior

Mug très sympa, bonne qualité.

Sieht super aus wenn warmes drin ist
