Its nice to pay top dollar for something like this mug and then when it arrives, it meets or exceeds expectation. In the description it says the mug is not spill proof. Im not going to ague as to what actually constitutes spill proof or not, but the lid is pretty comfortably snug in there. It just might survive a fall or drop without flipping open anyway.

My 2nd one. Heavy, rugged, and durable. I will buy again.

Yetis are the best and only cups to get.

My kids have been all over me to get a Yeti, Ive held out until now but finally since my hubby loves his big cold drink Yeti and just purchased a 2nd one for the office I caved in. Im a huge coffee and hot tea drinker and I work a lot, I keep a cup full at my desk most of the time and now that its getting colder I move to one of my tumblers and thought this Rambler would be a perfect cup for me. My coffee was cold in 30 minutes and the lid began leaking onto my shirt about 20 minutes in. No good, Ill keep my old Starbucks tumbler and toss this Yeti in a drawer to collect dust. Bummed to have spent so much on a cup that doesnt work!

The number one thing I like about this cup is the sliding lid stays open while you sip and stays closed if the cup tips over. Its clearly durable but unfortunately doesnt keep the liquid warm. With the surface area to volume you cant expect it to keep liquid warm for hours. My first use was from my home coffee machine and I took it outdoors into 40° temperatures. The coffee got called just slightly slower than an ordinary coffee cupboard. Im still happy because it wont break when I drop it and wont spell its a great looking cop but again dont expect the small size cup to keep your liquid too warm in colder temperatures.

I love this coffee cup. I have had it for about a month and I love it so much that I went out and got the travel mug, and I got the large 36oz thermos for Christmas. This does a fantastic job keeping my coffee hot. The only issue is that I need to wait a little while to drink it because the coffee is too hot. My dad solves this by filling it with cold water to drink on the way to work, then he buys coffee on his way to work and fills it once he finishes his water, that cools the cup off enough that the coffee cools to a drinkable temp right away, but still stays hot while he drinks the coffee. The other thing I love about this mug is that it is easy to clean. Usually the close cover on the coffee cup is a pain to clean, but this one is magnetically attached, so you can just pop it off for cleaning. My dad has told me to get one of these for a while now, but I thought $30 was too much for a coffee cup, but now I am sold.

I love the design of this cup. I have been disappointed in the temperature control though. It doesnt keep my coffee hot long.

LOVE! We have a decent amount of yeti products so I knew this was going to be good. Having a son I have to heat my coffee up multiple times throughout the morning but with this yeti mug I don’t have to heat it up at all, even if I leave my coffee for 30 minutes! I’ll come back and it’s still hot! Just remember to keep the sliding cap closed.

Yeti is great, but Amazon packaged it poorly and the cup arrived dented. I was disappointed since it was intended to be a gift.

The Rambler is a decent insulated tumbler. It does keep drinks cold or hot for an extended period, but I found it to be quite bulky and heavy to carry around. The lid is also quite difficult to clean properly. While it does its job of keeping drinks at the desired temperature, I expected more from a product with such a high price tag.
