THILY 22oz Stainless Steel Vacuum Insulated Travel Tumblers - 6 Pack Powder Coated Coffee Mugs with Lids & Straws, Leakproof & Non-Slip, Keeps Drinks Cold/Hot for Hours - Perfect for Office, Gym, Hiking & Road Trips

My dad and my niece loved their glassesFirst. I absolutely love these tumblers. 90 degrees in the sun and my drink will still be ice cold.Second. My evening 11p ice and a pop, 2p following day, still ice and not flat.Third. I own the 22oz and the16oz tumblers, which I love both BUT for some reason, the 16oz doesn’t ‘hold’ as long as my 22oz which is extremely disappointing. Basically, if I don’t keep a coozie on the 16oz and haven’t finished my drink in a short time, I’m dumping it out due to it being watered down or warm and replacing it often thru out the day. Also, with the 16oz, if you add ice (I’m talking like 3 cubes out of a refrigerator ice maker), you will not get a full 12oz can in it.This cup is amazing. I like the slim cups for ease of holding. This cup keeps ice very well. I can leave a cup in my car overnight in the garage in the summer heat and still have ice the next morning. Recommend this purchase.Needed an insulated cup for my golf cart. Fits perfectlyLike that the ice melts very slowly, so I can have cold water by my chair continually. Easy to hold and doesn't get cold on the outside.The only reason I give it a 4 instead of a 5 is that the beverage doesn’t always flow well when just drinking, not using the straw. They are attractive, well made, and keep your beverage very cold for a long time.I have used this mug daily for over 15 months. It suits me perfectly. I love the slender size and the extended depth and width of the lip make it perfect for hot drinks (I use it almost exclusively for coffee.) When you take a sip the coffee is drawn into the lip where it has just a second to cool off before you sip it. I never burn my tongue on hot coffee because I have just enough time to gauge the temperature before I drink it. The insulation works great too. I was a little disappointed that coffee residue was building up inside the slider parts, but I’d come to expect this of most coffee mug lids. Then I read in the product description that you could remove the slider by popping it out from the side WITH A FLAT OBJECT. It works! The parts clean up easily (I used a toothbrush) and pop back in good as new! TIP: When you first put the lid on a hot beverage, leave the slider open for a bit. If you put the lid on closed without allowing some air to escape first the lid may pop up just a bit and leak if sloshed. Just open the slider before you put the lid on. I fully recommend the THILY 16 oz Insulated Skinny Tumbler Travel Mug.I do not drink enough for the tall ones or the wide ones, but this is the perfect size. It keep my drink cold enough that I can still drink it in the morning when I first wake up, but it does not keep it cold 12hrs. I have not used it for anything hot. It is also beautifulReceived 2 days ago. So pretty!!Kept my coffee hot for hours on first day with lid closed. Today I had left the mouthpiece open and it kept the coffee warm for hours (3ish hours until I was done).Easy to clean. I saw 1 review of complaint that the lid cannot be cleaned, but the sliding part can definitely be popped off with a flat object like a spoon or butter knife to clean. I had emailed Thily and they sent a video back showing exactly how to easily pop it off.These photos were taken with water inside the tumbler (yes, you can turn it upside down above a laptop!). Fell in love the first time I held it in my hands -- it's so pretty and is exactly what a good tumbler should be. Feels really well made. It's easy to use because you don't have to fumble with screwing the top on. The silicone-lined leakproof lid is easy to manoeuvre. The lip is really nice to drink from, but the trickle can be a bit slow so that's one thing to be aware of if you like taking big gulps. On the bright side, you can turn it upside down completely and not make a mess while you try to extract as much content as you can. Haven't tested out how heat-insulating it is yet, but the interior looks similar to any other container with decent temperature-keeping potential so I'm not too worried. Overall, I'm super happy with my purchase and will be enjoying early mornings with an extra touch of sparkle :)This bottle is attractive and certainly keeps hots hot, and colds cold. Nice to have the proper size of stainless steel straw included. However, you have to pull the cap off to fill the bottle, and this can be a struggle. I am thinking of people with weak, arthritic or otherwise disabled hands: I don't think it would work for them.As delivered, I found this reusable mug sub-optimal. I was never intending to use it for cold beverages, and the first time I put hot coffee in it, put the lid on, slid the lid closed, went to work, and the lid exploded off the cup from the build-up of steam inside the cup. When I drank out of it, there was barely any flow because the hole in the lid was too small and obstructed by the rest of the lid.I looked at the rest of the reviews and someone showed how to remove the slider with a spoon. I popped it off, heated up a nail, and melted the hole larger. Then, I took a sharp metal skewer and forced the rubber plug out of the end of the slider (furthest away from the drinking end). Now when the lid is sealed and on the cup, there’s just enough air flow to prevent the cup from exploding in my car again. Win! It keeps my coffee toasty warm for my entire “short” work shift (4 hours plus travel time) so works great!Only 4 stars because I shouldn’t have to purposely destroy the lid to get it to work better (plus, I can see that slider snapping one of these days when I remove it for cleaning every so often)Omg. These are A-mazing!!! They keep drinks sooooooo cold. I am super impressed. Even keeps ice unmelted in it over night! I had my best friend buy one too because I was so impressed. Great job! Only downside or thing you have to get used to is the cold cold drink in a metal straw, SUPER cold drinking it too lol
