Been shopping for a replacement for my husband... I don't care for most of the choices out there. Many years ago (like probably 9 years?) we snagged a double walled stainless steel one at Barnes and Nobles. It cost $16, and at the time I thought about getting 2, but thought it was a little pricey, so I didn't. It has a really nice rubberized grip that runs around it where you hold it to drink, so your hands don't burn on the hot stainless. It has a single piece plastic top with a simple slide opening. It fits perfectly into hubby's deep cup-holders (it gets wider at the top, so it isn't super tall either). It has begun to wear and get banged up after years of getting dropped and rolling around in his car floorboard when empty, etc.
Everyone I pick up to consider, has plastic inside. Or is huge and won't fit in a normal cupholder. OR has a HANDLE. Which he doesn't like and probably will interfere with his cupholder (deep, did I mention that?)....
Such a pain. I shoulda bought 3 way back when.... :(
I did find something that might do the job last week at a college bookstore. Only time will tell... when he opens it under the tree... lol
