This mug does only a fair job of keeping coffee hot.  It will absolutely NOT protect your shirt, pants, carseat, or anything else from spills and drips!  The lid does help to keep the coffee hot in that without the lid it is exposed to the air.  That slight benefit and it's attractive appearance are the only advantages I found.  If you have NO concern about leaking/dripping, this mug is sufficient, however, the Contigo Autoseal West Loop is a much better product, and for essentially the same price.  I have returned my Timolino PABLO-46GREmug and purchased 2 Contigo Autoseal West Loop thermal mugs in 2 of the many colors available (I like lilac & gunmetal).  This Timolino thermal mug, in my opinion, should cost only $10 due to it propensity to leak!
