Question: Is the mug stainless inside?
Document: After reading all the rave reviews, I was rather disappointed after a few uses of this cup. The inside separated rather quickly from the outside plastic. I think I will stick with stainless steel.
Had bought all kinds of mugs for my coffee-loving husband. None satisfied his needs like these mugs. My misses included ceramic, stainless steel, plastic. He wanted a mug with a wide bottom and a rim which would operate easily and not burn his lips. He raves about these mugs and loves them so much he asked for more. I was so happy to find these still being offered as a pair at a most reasonable price. Hope these stay in production a long time!
I was always spilling my coffee in the truck when responding using a regular coffee mug. Not these, I respond to the call, take care of the emergency and my coffee is hot and ready on the floor of the truck when I'm ready for it. I also forgot one of the cups on the  back of a truck and it fell off. A good 3 foot drop, no damage and some of the coffee was still inside.
I got these for a Christmas present a couple of years ago...they do a good job keeping liquids warm inside and the wide bottom is great to avoid tipping the mug over. The only problem I have is that after about a year, the mugs started to occasionally leak where the lid snaps onto the mug. It's not really bad, but the first couple of times it happened, it dripped hot coffee on my shirt!
I like them because they have a wide base and don't easily spill!Coffee will stay hot for at least a couple hours, so nice to head outon a short trip. I used to own expensive stainless steel thermosesand have found that these are much more functional and enjoyableto use!
They do a very good job of keeping hot drinks hot for hours. I'm sensitive to a weird taste when coffee is kept in stainless, and I didn't want to have to baby a glass Thermos. Their fat shape prevents using them in most car beverage holders, but does keep them from turning over on desks, etc. I should say that the reason I've purchased these several times is that I lose them at work.My only complaint with them is that the top looks leakproof but isn't.
I'll be shopping for another, truly leak proof insulated mug.
We had been looking for this type of insulated mug for quite some time and were happy to find them at last.
This mug is NOT a travel-type mug, and is not sold as such. Keep that in mind and you won't be disappointed.
The only problem we have with these mugs is that one of the lids is very hard to remove from the mug. Otherwise, we love them!
