Ello Oasis 18oz Stainless Steel Kids Tumbler with Handle Retracting Straw 100 Leakproof Double-Wall Vacuum Insulated Kids Water

This cup is so cute, keeps water cold over night. The straw is not a soft one, but I love that the straw slides down to prevents germs and it is no leak. Perfect size not to big or heavy. Love the lemon design. Read more

Favorite water bottle ever!!! So cute! Keeps drinks cold like most tumblers. I will say it was better at that when it was newer though. I've had it for I think a year now and no problems. Straw works great and easy to clean. My husband bought one too! Read more

This is the first time I’m writing a review for a product I’ve ever purchased, just because I’m so impressed and happy with this tumbler. I’m a mail carrier, and was looking for a good sized tumbler that not only would keep my coffee warm all day, but also wouldn’t spill or leak. Since I don’t have a cup holder in the mail truck, I stick this tumbler in my bag and go about my day. No spills, no leaks, it doesn’t even “sweat” if I have cold water in it, that’s how good it is. The retractable straw is also so smart and a great design. I was worried at first that even though it retracts, there would still be some leakage. Nope! It’s more sealed than a vault. It also makes taking a sip much easier to do since I don’t have to worry about spillage when drinking. The handle is also great, easier to grab and hold onto the tumbler, and also helps to stop it from rolling around when I’m driving on bumpier roads. I’ve had water bottles and coffee mugs before that boast about keeping beverages at a desired temperature for hours, and 90% of the time it’s never been true. Not this tumbler! I’ll make a hot coffee at 6am and by 4pm, that coffee will still be hot, which has been a godsend when it’s below freezing outside. I fully trust that once it gets hotter out, it’ll keep water or iced coffee cold all day long. The colors are also very nice; but I’ll be honest I wasn’t really going for looks as much as I was going for a product that can withstand a bit of a beating without getting coffee everywhere, and in that regard this definitely hits it out of the park. I love my tumbler and I’ll definitely be buying another in a larger size. Read more

I've developed a somewhat obsession with 40 oz. tumblers. I'm on meds that make me thirsty, so I keep one next to me 24/7. I've tried many different brands, and most have something great to recommend them, but come up short in other areas. My biggest complaint always comes down to leaking. Most of the double-walled tumblers will keep your drinks cold for at least 24 hours when filled with ice added at the beginning. But some have issues with lids popping off and all the ice and drink exploding all over the floor when tipped over. (I've had more than enough nights ruined by reaching over for my tumbler at night and accidentally knocking it over and having a huge mess that I have to jump out of bed and clean up. It's not easy to fall right back to sleep after that!) For this reason, I always look for screw on lids rather than the ones you just push on. The next issue is if they tip over and leak from the straw opening. For that issue I look for mugs with silicone seals around the straw opening. But even then, if it's tipped over, your straw opening lands on the floor even if it doesn't fall out of the mug and needs to be cleaned before using again. When I saw this tumbler, I was surprised to see a retractable straw. I wasn't sure how it would work, so I watched a video of it in use. The top of the straw is the firm plastic that I prefer to use. (The soft silicone ones just feel weird to me - personal choice issue....) However, the inner part of the straw is soft silicone and bends over when the tab on the top is twisted around and the upper straw is then drawn down into the tumbler. Genius! It really does seal it tight as well. I tried filling the mug full and then held it over the tub and vigorously shook it to see if anything would come out. Nothing! As an added bonus, there is a little 'bump' thing on the side of the lid that makes it so much easier to get a good grip to help unscrew the lid. As a 71-year-old lady with nerve damage in my hand, I've often had to ask my husband or sons help loosen the lid for me. What a pain to have to wait for help to fill your drink! As for the normal functions of all tumblers this size, it does indeed hold 40 oz. of ice and liquid. I fill mine with ice first thing in the morning then add more cold Diet Mt. Dew throughout the day (and night if needed). I still have ice left the next morning and the drinks stay cold the whole time. I've left my mug in a hot car for several hours as I shopped and it didn't seem to affect it at all. It's definitely well made with a comfortable handle that even has a silicone insert at the top of the handle to help with the thumb grip. The coating is slightly textured to help hold it even when wet. It's not any heavier than any other tumblers of its size and easily fits into my car holder. I do wish it came with a silicone bottom to help keep it from scratching surfaces and slipping around when reaching for it. But I've gotten used to buying silicone boots here on Amazon for my previous tumblers, so I have several to use. I just ordered one to match this one's color better than the ones I already have. (Yes, I have a shelf full of tumblers with boots - I keep them all to use at picnics for everyone to cut down on the amount of ice we need....) I do wish they came in more colors, but that is not a deal breaker. I'm sure they're waiting to see how well they will be received before they release them in all the colors their other mugs come in. Value wise, they are much cheaper than most of the other mugs I've seen and or bought. One other note. Most of these types of tumblers state they are not to be used with carbonated beverages. I can't drink the amount of water I need to stay hydrated - for some reason water seems to make me feel thirstier and if I drink enough, I get nauseated. So, I decided to investigate and found that on the Stanley site it stated that most carbonated beverages are stored in stainless steel barrels before distribution with no issues. The main thing that I've found is that you need to make sure there is a way for the carbon dioxide gas to escape, or it can do the 'Old Faithful' spurt when you open them. (I've had that happen several times! I quit using any type of mug with a sealed lid without any way of venting) Even though these don't leak, the gas can still slowly escape around the straw opening. I've bumped and shaken my mugs a lot and not had any problems with the ones with straws. I haven't found any erosion in the linings of any of my mugs, even the ones I've used for years. The stainless steel doesn't seem to affect the taste at all. All in all, this is my favorite tumbler of all the others that I've bought. I have at least 8 other brands and this one outshines them all. The only thing that remains to be seen is how well it will hold up. I will update in the future if I find any issues. Read more

I have a ton of cups/mugs/tumblers, whatever the official name is for these things 😂 I have BruMates, HydoJugs and off brand one and now two of these Ello Oasis. The pictures are of the purple one in 30 ounce, but the review is the same for this pinkish 40 ounce that I also have. I use mine for the gym, just everyday water or electrolyte consumption and one to keep on my nightstand. I had to laugh at the review above claiming that this mug is “heavy” 🤣 It’s actually the lightest of all of mine, except the cheapest off brand one I have. Also, if their cup arrived chipped for whatever reason…send. it. back. 🤦‍♀️ Also, the straw configuration is *not* difficult to figure out 😏 Okay, now that that’s out of the way…I really do love these cups! I love that the straw is completely hidden and unexposed (as long as you turn the “dial thingy” completely) it 💯 does not leak (again, as long as you close the dial completely) it keeps my beverages cold plenty long enough, the colors are great and they’ve fit in every cup holder I’ve put them in (the reviewer above must have some super weird cup holders or they just aren’t smart if theirs doesn’t fit 🤣). The coating on the outside is the exact same as my HydroJug and my two year old HydroJugs have zero scratches, so it’s definitely decent quality. Now, to the reason(s) I knocked one star off…if you put anything with a flavor, I’ll use a scoop of cherry electrolytes as an example, and wash it by hand, the smell and flavor is quite hard to get rid of from the straw and its mechanism. If you put it in the dishwasher, it comes off fine. Also, I wish it had a silicone bottom or at least a boot I could purchase for it, as the bottom is just the stainless material. It’s the same diameter of the HydroJug, so I’ll probably just purchase one meant for that type. That’s really my only criticism, otherwise these are great and not way overpriced like the other brands. Read more
