I have an Ozark 20 oz cup, only issue I had was that while I habitually sit the cup between my legs while driving, I usually ended up looking as if I pissed my pants. as so many times, while full, it tipped to the side and the coffee poured out on to me. For Christmas I got a different lid, one that has a slide that closes off the drinking hole. I LOVE it. I also got a handle for it too! Which is another very much liked addition.
As for coolers, I won't pay the price. I have one that was supposed to hold ice for 5-6 days, a Coleman I think. It serves me well. For my Jeep, I have a Wal Mart $20 one. There is a same size, same everything also for $10. I had one of thise first. Seems the difference in the two was one was hallow, the other was foam filled. On the hottest day wheeling, the $20 one with 4 frozen soda bottles, will hold any of my drinks at a temp that is very tolerable.
Biggest issue I have had(and I am on my 2nd extended ice life coolers) is people sitting on them, bowing the lids and making them ineffective for the long haul.
Would I have a Yeti? I'd love one, but like I said, the difference in Money, will buy a lot of ice. I see some used ones every now and then, shoot out a low ball offer(what I could afford and feel good about) but so far, it hasn't been enough.
