Review on Mug Warmer: Keep Your Coffee Hot for 8 Hours with Automatic Shut-Off and Adjustable Temperature Settings - Red Electric Cup Warmer for Coffee and Tea by Vanessa White

Really great! I love finally having one of these. My coffee ALWAYS gets cold before I can enjoy the whole cup. I've tried many different things, cups, poured different amounts, and I always seem to get distracted or end up not being able to enjoy everything until it gets too cold. So this is definitely the perfect part for me. It has three different temperature settings that are easy to select/change. It can keep it warm for up to 8 hours (e.g. a full shift a day if you use it at work) with an auto shut off feature which is great for safety and helps me remember because I already have enough little things to remember. I have no complaints or questions to report. Definitely what I would recommend! It can also be a good gift idea.
