I purchased this travel mug about 2 months ago. I’ve used it everyday since I’ve received it in the mail. I looked at many online and thought this would be the best purchase, and for me it was. I love my coffee throughout the day and was wanting something to keep it warm. This is the mug to get if that’s what you’re looking for. I wasn’t crazy about the price but now, I think it was well worth the money. It keeps my coffee warm throughout the morning and I charge it back up during lunch, keeping it with me throughout the afternoon while at work. I’m a supervisor and most of my day is driving from job to job or meeting with people during the day. So, this allows me to have warm drinks while driving most of the day.
