Title: Buy this!
Review: This is seriously the neatest office gadget I have. I have switched from stainless steel coffee mugs to a porcelain mug with a lid because I do not like the taste of my coffee/tea in the stainless mug even though the stainless mug keeps my coffee hot until its gone. The problem with a porcelain mug is that it doesnt keep my drinks hot for long. I can take as long as I want to drink my coffee/tea now, and it is still the perfect sipping temperature even after an hour. I think I may get one for home on my coffee table for when I get discracted with the kids and leave my coffee until it is cold and then have to throw it out.
Is the review positive or negative?
