aokiwo 20oz and 30oz Tumbler, [2 Packs] Stainless Steel Insulated Tumblers Double Wall Vacuum Tumbler Travel Mug with 2 Lids, 8 Straws, 2 Brush and 2 Handles（Black）

I use the larger cup for cold stuff and find that the only way that it really keeps things cold for longer than 4 or 5 hours is if you fill the cup completely with ice, which really affects how much liquid the cup holds. I prefer more liquid than Ice.I use the smaller cup for my coffee and it does seem to keep it hot for longer, it is the perfect size that it fits in my Keurig to brew straight into the cup! I find if I want to keep it hot for even longer filling it with really hot water for a minute or so before I fill it with my coffee does the trick.I do not like how the handle on the smaller cup fits. It is almost like it is to big and the cup slides down in it until it is all the way to the to of the rim and just below the lid. When you try to drink out of it you are dealing with the thickness of the handle under your bottom lip and I fear if I move it wrong it's going to pop the lid off. I don't use the handle on the smaller cup because of this.The handle on the larger cup works perfectly and does not sit as high on the cup.I love the color of the cup (teal) and the straws are a perfect size match- having two straw cleaners is also nice. The straws came in a nice bag which is perfect to toss a in my brief case and carry them along for use with other things as well.Overall I will purchase again ( a different color to mix things up) as it does meet my needs.

Ok.. pro’s… I use the big cup and I love the handle so no slip out of hand, kept my coffee hot for 2 hrs and warm for another 1.5 hr. So total 3.5 hrs and still warm. And I like my coffee, steamy.. so just FYI. Cold.. well my daughter uses the tall skinny one and puts ice and her coffee and kept her coffee cold for 4 hrs. But we are in 80* weather and 3 hrs in full sun. Oh.. straws, daughter loves the medal straws, she says the straw cleaner is perfect. Oh also, dishwasher safe. But I put mine on top shelf, that way not so much heat and drying ( also, have washed it 10 times by dishwasher, at first was washing by hand/ but all good) Now leak proof, yes I have tipped it on accident alittle when it was very full and nothing came out the side lid, and nothing out the top holes. But did I turn 45*….NO.. but about 15-20* tip.. on accident, with very hot coffee, so I was happy no drips or spills. I probably should try it over shink with just water….***update.. just try it, over shink with water and I turned it 90* (fully upside down) and even shock it alittle and I was nervous,thinking I’m going to get splashed due to the cup was all the way full and warm water. But nothing.. so yes leak proof. I even wiped with paper towel to make sure nothing dripped and after 4th shake(didn’t hold the lid either/scary), that is good..I maybe got a tiny, i mean tiny little wet dip. I mean tiny tear drop. So yes very good.

I use the large Glass for iced drinks and it seems to keep the items in it cold for minimum of 8 hours.I use the smaller mug for HOT drinks. I like the size of this mug. I have a water dispenser that gives hot and cold water and I keep this mug on the cabinet here it so I can fill it with hot water for tea. I sit the mug with the teabag in it on the table. Started my breakfast, went to take a sip of the tea and the handle came up over the top of the cup. Just by luck it was close enough to the table that the cup just went back own on the table and didn't spilled only a splash on the table. I did not have the lid on it, so had it tipped over I could have been burned badly. Once I emptied the mug I put the handle back on from the bottom and it seemed to hold, but I will not trust it again. I will probably super glue the handle in place to see if that will solve the issue if not I will discard the mug.

They lose a star because the handles can be a pain (falling off when you dont want them to and the 20 oz. they go all the way to the top so your lip is touching them when drinking making dribbles quite common. I just leave them off the 20 oz from now on) Also one of the tops on the 30 oz stopper came off, no biggie for me as they dont really leave the house but if you want it for travel it would be a problem.

I absolutely love these cups! However I think the only down side for me is the rubber piece on the big cup lid always slides off or up the small cup doesn't have that issue. Also the handle on the big cup the top part is perfect but the bottom of the handle doesn't sit correctly do it slides easily. Other than that like I said I absolutely love these cups!

Ordered the teal blue but got black. Disappointed. But they are nice mugs.

I love these. I don't drink out of anything else for cold beverages. I am spoiled to the point of needing a lid and straw for anything cold I drink.

Haven't had them that long. The metal rim along the top (where screw cap is located), now has RUST spots! It's a water jug; shouldn't RUST if water touches it! OMG.
