The media could not be loaded. I love these overall, my drink stays hot for hours, and I love that the lids slide closed and vacuum seal it shut. As mentioned in other reviews, the lids are a hassle to take apart for cleaning. I had originally tried what one reviewer said and put it into the closed position then used the handle of a spoon (forks are dangerous lol) thru the mouthpiece to pop it off, then back on forcefully- I DO NOT RECCOMEND THIS! The grooves on each side of the sliders were getting chipped, and this was only after a few days of use/washing. This in turn caused what another reviewer had mentioned- where my slider was popping up when in the closed position, and the vacuum seal function doesn't work anymore. I attached pics and video of the broken pieces.CUSTOMER SERVICE IS EXCELLENT! I immediately contacted the seller via email as suggested on the packaging insert, and they got back to me within half a day. I explained the situation and sent my pics/videos and I am able to get replacement lids.HOW TO CLEAN LIDS: I suggest just sticking them into the dishwasher, slider in the middle position- neither open nor closed, and set upright on the top rack so the water can thoroughly wash inside and rinse out, and dry out. (make sure to remove the seal ring and wash seperately) I did this today and worked well.-OR-I have also found that because of the grooves, if you actually wedge a spoon handle along one side of the slider (side where the grooves are) and push downward toward the opposite groove, and pull it out from just the one side where your releasing the groove, it'll keep them better intact. (I hope that makes sense!) And you'll have to basically do the exact same thing to get it back in without snapping the grooves off- and it was easier to do this technique with slider in the middle of the lid.Sorry for long review! But I really do like these! The colors are beautiful (I got a 2 pack pink and gray) and they're overall sturdy and dare I say better than my yeti I've had for a few years now! The sliding lid with vacuum seal is such a cool feature, as long as you don't mind a little work to get them clean and keep them in one piece! I RECCOMEND!

I really loved this cup on my recent camping trip, I bought two and both were used every day and sometimes twice a day. It kept drinks insanely hot and had a very good seal. The cup feels nice for the price and is all-over a super versatile cup that I will use for many years to come. My only issue with the cup is the difficulty of cleaning the lid under the sliding mouth piece. I spilt coffee underneath the plastic and it was pretty difficult to get all the coffee cleaned out from under the plastic sliding mouth piece. That’s the only reason it’s a 4 star instead of a 5 star- I still really loved these cups just wanting to forewarn others of that!

I bought this item in 2022. It’s probably one of the best items on Amazon, to date, that I’ve ever purchased. During this past week it’s been a scorching 90 + degrees Fahrenheit, and the ice has remained ice even being left in the hot car for an hour. This is after using it for 3 years. It’s still in great condition. And well worth the price I paid. I highly recommend this brand!!!

The tumbler is well made, materials feel good and the lid fits snuggly. Ice will keep overnight and it does keep my coffee hot for an extended time.My big issue is the lack of a vent. Liquid accumulates at the opening and then rushes out. I hope they have a solution otherwise I'll need to return it.Update! Rating changed to 5 stars! Customer Support responded to my issue and provided a different lid. Thank you for listening and resolving my issue. I very much appreciate their customer care.

This tumbler is adequate.. it does keep beverage cold with ice longer than my previous tumbler, but not as advertised!! Description says keeps beverages cold up to 24 hrs, my experience is only about 12 hrs at room temperature!!!
