Rated 5 out of 5 by from Keeps drinks cold till the last drop! My wife loves it! She's the type who will enjoy her drink slowly. Unfortunately, even with a typical koozie she has a tough time finishing it as the last 1/3 of the drink will be too warm. So I decided to give her a Rambler Colster to try out. She was amazed at the result. Not only does it keep her casual drink cold, she feels that the drink actually gets colder over time. And the fact that there is no moisture on the Rambler when she holds it or puts it down on a table is another plus. Even though I knew how good Yeti products are, I was really surprised at how much she liked the Rambler Colster. She is now a huge YETI fan and swears by the Rambler! Thanks YETI!

Rated 5 out of 5 by from Best Rambler I have ever bought. My wife got me one for our anniversary last year and I love it. It keeps my beer cold even when its 90 degrees out. We were camping last year and I went to bed and left a half full beer and when I got up the next morning it was still cold enough to drink. So I order to more one for my wife and one so I can have one at home and one in my camper. I also told all my friends and they are going to order some.

Rated 1 out of 5 by from got for Christmas---am very disappointed with this The gasket on top will not go down on a 12oz. can far enough to get the gasket to start on the threads straight. Gasket will start on crooked EVERY time you try to put a cold soda in it.
