My second (and final) Ember mug has given up the ghost.
After a year and a half, my second Ember Mug doesn’t want to hold its charge. After a chat with their support, they’ve stated that it is “at least 6 months past our 1 year warranty - the battery may not be able to hold a charge anymore” (I’d estimate it’s around 6 months past). Now, I don’t expect batteries to last forever, but if I’d known in advance that they only expect it to last not much longer than the warranty period, then I probably wouldn’t have purchased one, never mind two. Perhaps it’s there in the small print. They’ve offered me a new mug (just the mug - no coaster or charger) for around £65, but that doesn’t seem a good deal any longer knowing it’ll likely fail again in a little over a year. Time to look for alternatives.
