  • Essential for human life
You cannot live without this cup in your life. My “friend” stole the first one I ever owned and I went a few years without one. I don’t know how I managed to live without it. This cup is never not in my general vicinity. I’m going to buy another one because I use it for water but sometimes I put tea in it and it’s hard to get the tea stains out but that’s no fault of the cup tea just stains everything. So I’ll have one for water and one for tea. Tea stays boiling hot for hours and ice stays frozen for hours this cup is just a dream come true. You will drop it many times over the course of your life and it will NEVER break. The first one I had had been through some serious abuse and it’ll show some scars from extra bad drops mostly on the bottom but the textured finish hold up impressively well. It’s really hard to scratch the paint off you really have to try in order to mess up the finish. When you drop the cup from 4ft on to a hard floor there’s about a 50% chance the lid will come off and your drink will spill. It’s unfortunate but I would rather live with that risk than have to unscrew a lid every time I want to refill. I drink tons and tons of water so simply being able to pull the lid off is worth the risk of the drink spilling when dropped. Easy to clean and keep clean, if I’m only using this cup for water I rarely have to wash it I just rinse it out often and it stays crystal clean. Love the magnetic open and close. The cup does leak slightly if you flip it completely upside down but it’s not a lot. Since I pretty much only drink water from these cups I don’t care about a few drops of water leaking occasionally. Just keep the cup upright and it will never leak. Don’t drop the cup on to concrete from 4-5 feet and it will never spill, and even if you do the lid might not even pop off. The lid needs to land in a very particular way for it to pop off when you drop it. One thing I will guarantee is that if you buy this cup it WILL last longer than you do. I’m sure the seal will begin to degrade after a reallllly long time but I used the first one everyday for over 5 years and the seal never even began to degrade AT ALL. The cup is genuinely built to last a lifetime. Your children can inherit the cup. They should inherit this cup. Buy this cup and know your grandchildren will be drinking from it long after you’re gone. It will be a nice way for them to remember you. They won’t care about your stupid coin collection but they will greatly appreciate your epic yeti cup. This cup reigns supreme and is worth more than it cost. The price is like kinda hard to stomach but then you hold it in your hand, put it to your lips, and realize you made the purchase of a lifetime. I had a black one before, spiced it up this time with a green one, which color should I get for my next one? ... show more

  • very nice product!
Color: Venom Size: 20 Ounces
i was never a Yeti fanboy......but after years of using all these different types of tumblers, i finally tried the yeti.......i love it!!! it isnt the type to toss in the gym bag or anything but, use it as a normal stand up coffee mug for cup holders and such, it is a 10/10 for sure!! it doesnt have a screw on lid thats hard to remove or any other overbuilt lids like what's out there, its just a basic get the job done well coffee mug, for the $20-25 they cost, cant beat them!!! and your coffee will still be hot 2 hours later! ... show more

  • Fun design and go-to mug
Color: Cape Summer Camp Size: 20 Ounces
Love the sticker design, colorful and fun!! The mug holds true to keeping hot liquids hot and cold liquids cold. It is easy to clean, especially the lid which is an issue ive had w other brands. Excellent purchase!

  • Replacing all of my cups with these
Color: Cape Summer Camp Size: 20 Ounces
These cups are awesome. Keeps drinks both warm and cold, perfect size (not too big but not too small), no condensation, and the magnetic lid technology is killer. I have a huge issue with a coffee cup lid that is hard to clean, it really grosses me out if I can’t properly scrub everything- and the lids on these cups eliminate that completely. I also love swapping the magnets for different color ways. The designs are very cute and tough too, no peeling or cracking or scratching from my metal sink. Love. ... show more

  • Keeps drinks cold
Color: Sea View Size: 20 Ounces
I really like this YETI tumbler. It feels very sturdy and well made, and it keeps my drinks cold for hours without the outside sweating all over everything. The 20 oz size is perfect for everyday use and fits nicely in my cup holder. I also really like the MagSlider lid because it’s easy to open and close and helps prevent splashes. It is a little pricier than some other tumblers, but the quality definitely feels like it will last a long time. Overall, I’m very happy with it and would definitely recommend it. ... show more

  • Love my Yeti's!
Color: Navy Size: 20 Ounces
Consistently a great product. I love this size tumbler for the beach. It is light but holds a lot and keeps my drinks cold. I have two red ones and bought this time in blue for a friend of mine. Easy to handle, large enough but not too big. I am not a fan of the straw cups, so the top on this one is perfect for me. Came packaged beautifully, great value! ... show more

Color: Navy Size: 20 Ounces
It’s my work coffee cup and hold really hot heat for 4 hrs and warm for 3 hrs so a total of 6 hrs. Of course this is if after every sip you close the lid. Also the lid does leak a bit but as long as you keep it upright then you’re good. Easy to use and seems durable and doesn’t change the taste of the coffee. ... show more

  • My go-to tumbler for water and coffee
Color: Red/Badge Size: 20 Ounces
This has become my go-to cup for both water and coffee. It does a great job holding temperature, whether I’m trying to keep water cold or coffee hot, and I use it regularly. I also like the MagSlider lid. It’s simple to use and works well for drinking on the go. My biggest complaint is that the lid isn’t leakproof, so I wouldn’t throw it in a bag or expect it to prevent spills completely. The temperature retention is very good, although I do wish it held the temperature for even longer. Overall, it’s a durable, reliable everyday tumbler that I reach for often.My go-to tumbler for water and coffee ... show more
