This is the first review I have ever felt compelled to write. This is a remarkable product. I bought the 20oz (30oz is on the way). I tested this in my kitchen against a Tervis. Filled both with ice, then topped off with water, closed the lids. After about 4 hours, the Yeti still had all ice, Tervis was just water. I dumped the Tervis and put it away, drank the water from the Yeti, left it on the countertop and went to bed. Next morning, went to Church and ate lunch. Got home at about 2PM and it still had a lot of ice inside. I tested it again Monday (Aug 4) 8AM I filled it up with ice & water. Drank the water on the way to work and left the Yeti in the cupholder in my truck all day in direct sunlight. At lunchtime, all ice was there and had formed a single piece of ice. At 5PM, still about 3/4 full of ice. At 8:15AM Tues, nearly all water, but still had ice about the size of a golf ball inside after being left in my truck 24 hours on a 100 degree day. I know, it doesn't seem possible. I can't believe how good the Yeti Rambler really is.
I have ordered the coffee tumbler and just received the koozie after a very long waiting period. The bottom of the koozie has two dents in the stainless steel. I will not return because it took so long to get the koozie in the first place. Products are great but not happy on the delay and the dents. Coffee tumbler I had no problems what so ever. I would recommend these products. I bought coffee tumbler for my husband and now I also would like to have my own tumbler. Keeps the coffee nice and hot!!!!
Best stainless steel tumbler you can own, hands down keeps drinks cold or hot for hours.
great product and customer svc thank you
