Love this ! and I love the fact that I can match it with my 26th and straw cup for the days where I need hydration and a little fun in my drink cooler. It’s orange is my new favorite color and I would be ecstatic if it came in the colster also

Lid doesn’t get tight

The lid will not tighten, just strips out and keeps spinning. It keeps the drinks cold, just not secure. I have loved all of my yeti products but I could not recommend spending money on this. Very poor design from such a durable company.

Love the cups, do better on color selections!!

First off the product is great. Since we aren't allowed to "solicit ideas" per your policy I'm just going to have to put them out in the open vs a private email.. You guys are struggling with the color selections.. not sure why because there are 1000's of variations you can choose from these days with modern technology FYI. The red has already been played like 4 yrs ago, I have one... There are multiple other colors that are just TOO CLOSE to each other it's like an afterthought.. is the color guy sleeping? Do better w the colors. Dont be lame. Also, a new version of the old camo will kill, maybe digi camo.

Can coasters are the best

I have 12 can coasters, and a few ramblers, a couple tumblers and 2 coolers. The can coasters are my favorite and most used. I just wish can coasters for the mini cans of soda were a thing. For the 7.5oz cans.

Fix your loose colster lid/rim to stay tight

To all people with loose rim/lids on the colster. Replace the cardboard circle that goes in the bottom like came in it originally. I take cardboard and cut out a circle and drop it in. This will raise the can up a touch and lid gos on tight pressing down on can. The cardboard give it resistance and lid and can dont move. Have Never had an issue as long as you keep a cardboard circle in bottom. Make sure its thick enough to raise can up you may need to press down on can a little if up to high. Replace every few months. Love these colsters I got one a year ago and now own two both with the og rim not the square off fat rim can't stand that. Stay with og rims. I won't purchase one with square off rim/lid. Hope that helps yall. Good day my friends

Great features

I recommend this product I found it extremely useful and one of the best at managing cold and hot drinks for almost 24hours in most cases.

LOVE, but missing one thing

Love these and in all sizes. If they add a super powerful magnet to one side of ANY of the Ramblers these would get a 5 star review from me.
