I have a favorite mug. I've had it for 8 years. Its a big wide bottomed Thermos stainless steel mug. It has a screw top, it is 20ozs (I have a matching Thermos...um, thermos, as well, so 36ozs all together). It had a one handed opener but I lost that bit a month after I bought it & found it I just stuffed a paper towel into the lid it sufficed for a car trip. (I now use Press & Seal over that when I take the mug to MOPS meetings). I lost the lid to this mug a few weeks ago. I searched the whole house for it. It was in the sink. DH said he put it in the dishwasher, but then it was just *gone*. So i had to get a new mug. My new mug arrived Tuesday. It is a Thermos E5 16oz travel mug. Nice mug. Not perfect though. It's just a tad too big to fit in the cup holder, but too small to wedge in the space between the seat & the parking brake. It also needs both hands to open the spillproof part. It is a good 'passenger' mug, but not a good 'driver' mug. I ordered it online so I had to go by description & photos. It will get used though. The fact that is truly is spillproof means I can take it to MOPS meeting & other places i go where there is little to no coffee available. But as a just to drive DS1 to school, its not so good.
It often happens that shortly after you buy a replacement for something that is lost, the thing that is lost then turns up. About an hour ago DS1 brought me his toy grill. The lid had gotten wedged shut. So I opened it. Inside the grill was the lid to my favorite mug! 30 hours after my replacement mug arrived & 2 hours after the packaging had leftover soup poured on it in the garbage can ensuring the new one cannot be returned.
