Absolutely Amazed!

10 years ago

My husband & I got the 30 oz Ramblers for each other for our anniversary, we love them & use them everyday! I put ice in my Yeti at 6am & it keeps my drink cold & does not get watered down in any way vs. the plastic tumblers I had all over my desk. Well no more, I am a Yeti user for life! My husband loves that his ice stays all day while being on the road and in traffic, and upon arriving home at the end of a long day, there is still ice! We're looking forward to our camping trips with our Yeti's. It's also nice that they can be personalized to be a reflection of you. I have been given so many compliments on my Yeti. Bring on a 45 oz +

Works great, looks horrible

5 years ago

My mother bought me my Yeti for Christmas 2018. As of July 2019 the color began pealing off. Now I have a Yeti that works great but looks horrible and I take it everywhere with me. I was so disappointed.

Unbelievably Durable!

8 years ago

I just wanted to you a story about my Colster. I have owned this Colster for about 3 years + now. It's my prized possession other than my Tundra 50. Well the other day I sat my Colster down on the tire of my Jeep while I was washing my wife's car. She needed to go to the store, so I told her to drive the Jeep. All of a sudden I heard what I later realized was my Colster, bouncing across our concrete driveway. Then she ran completely over it with the Jeep tires. Our Jeep has after market big mud tires. I just knew that my Colster was ruined. Well to my surprise, it was minimal damage! I still can't believe how tough this thing is! Amazing that it wasn't completely crushed! Just wanted to say thank you and keep up the great work. I'm a customer for life!

Team Yeti

9 years ago

I bought by first Rambler a couple years ago to keep drinks cold while watching my son on the baseball field. Drinks stay ice cold, during long hot days at the ball field. Since then I have tripled the size of my Rambler family and added a Hopper for cold drinks to share. The quality and performance of the Yeti products is unmatched, after listening to me rave about the products Yeti caught like wildfire on baseball team. We now consider ourselves "Team Yeti" because we have more coolers and tumblers than bats and balls.

Flawed Customized Tumblers

2 years ago

Let me start by saying I love yeti products. I have dozens of cups, tumblers, low balls, wine cups, etc., not to mention hard/soft coolers, buckets and so on. That being said, I just purchased 3 new tumblers and had them customized for my wife, daughter and I. One side was monogrammed and the other side had Tennessee Volunteers on it. All were flawed one way or another. On the art work side of both of the rescue red and the alpine yellow, all of the color was not removed down to stainless steel and on one the monograms there are lines outside of the border of the monogram. Pretty disappointing!

I really liked it, but then...

5 years ago

I really liked the tumbler, but then the paint started to flake off. They say they’re dishwasher safe, but I’m not buying it. Either hand wash, or stick with the stainless only. I’m bummed out that products at this price point are defective.
