Kikkerland Stoneware Thermographic Ink Battery" Ceramic Morphing Mug, White, 11 oz

The design works with the heat as stated, happy.

Bought as colour changing for my son's Christmas present and one use today and the battery washed off in dishwasher. And yet, it states dishwasher and microwave proof! Do not buy!

Love the idea of this mug and it's certainly sturdy, a good hefty size and looks exactly as described. Haven't tested it actually changes colour as it's for a gift but have no reason to doubt that it will.

It peels off the more you use it Don't buy you will be disappointed Not worth the money but mugs at the 99p shop

Che dire? Tazza termosensibile con batteria verde che sale, più bevi più ti si ricarica la batteria. Molto piacevole, fatta bene, ceramica di ottima qualità, ideale per un the del pomeriggio o caffelatte alla mattina, basta che sia bollente altrimenti la batteria non si carica. Ottimo come idea regalo, simpatica, l'ho cercata e adesso è mia. Feedback positivo 5 stelle.

Really bad quality and broke after the 1st wash. See the photo I uploaded...

Produit arrivé super bien emballé (c'était ma crainte) et en avance . Les motifs apparaissent tous quand on verse l'eau chaude (ça fait 2 mois plus ou moins )donc SUPER. Il ne faut pas mettre au MICRO ONDE ni au LAVE VAISSELLE c'est tout mais c'est pas la mort.

Die Tasse funktionierte leider nicht, nach mehrmaligen Versuchen entschied ich mich die Tasse zurück zuschicken! Find ich schade da ich sie gerne weiter verschenkt hätte.

Mug was smaller than I was expecting, but otherwise it is great. Colour changing works great!
