GeoyienInsulated Coffee Mug, Coffee Cup Travel Mug, Thermos Travel Mug, with Water Temperature Digital Display, Stainless Steel Smart Insulated Cup, Portable, Sealed and Anti-Scalding (510ML, White)

My daughter wanted a coffee warmer for her train trips to school and although this does a good job of keeping the coffee warm, she can't put it in her bag as it leaks if tipped over.

Well, first impressions are not great. As per the (somewhat mediocre) instructions, I cleaned it then preheated the mug with warm, approaching hot water, and left it for a few minutes.Curious as to whether it leaked, as per other reviews, I tipped it onto its side over a sink.... and the lid completely blew off into the sink. Spilling water onto my hand amongst other things. Hate to think what might have happened had that been boiling water. So not a great first impression.

Ho comprato questa tazza molto carina per bere bevande calde a lavoro.Con mia enorme sorpresa ho scoperto che non è ermetica e quindi ho versato il contenuto nella borsa.Per di più il display sopra è arrivato sgraffiato come se qualcuno prima di me avesse utilizzato la tazza.Una grande delusione davvero.
