Verified Purchase

ok, for those who didn't read the instructions... this cup is amazing, I'm on month two with it, no issues bottom of your cup, hold button until lights flash, choose your temp or whether to put it to sleep... don't forget to do that after your finished... this will keep your drink hot, so hot, you'll need lip balm for the burn if you aren't careful about one hour off charger, then recharge, repeat. my process is simple, fill, drink, repeat. I work up to 12 hours at my office, so do purchase if you are tied to a desk

Warm & Fuzzy

Such a silent night, to behold this triumphant desire. The night sky is a deep breath, as your lungs prove their worth. I find comfort in your shadow, away from the flaws lying under the sun. The warmth hugs my feet, and your neck greets my lips. Questions turn to answers, as feelings turn to daylight. It was then, I was sure- this feeling would be my last.

handy self-heating mug

This is a very useful mug. I like that you can use it on the charging base to keep your drink hot or remove it and still keep it hot for 2 to 3 hours. I like that it clearly shows the temperature setting right on the mug. It's nice that it comes with a travel lid to hold in the heat and keep it from spilling. It seems to be well made and has a ceramic lining. It takes a while for it to charge the first time and I recommend recharging it after each use. It works better at keeping hot liquids hot. I tried heating tap water to 135° it took 20 minutes or more to reach temperature.
