Copco 2510-9979 Sierra Single Wall Tritan Cold Tumbler with Removable Straw and Spill Resistant Lid, 1 Count (Pack of 1), Orange

I'll be right up front since others seem to take issue with one fact over and over, because this cup isn't double walled it will sweat if you use it for iced drinks. It's simple thermodynamics and if you're looking for a cup with which to travel, this might not be a good choice. That being said, for my purposes it's a fantastic cup and I'll go over the high points.First, it's inexpensive given the quality and materials. BPA free plastics, firm silicone sleeve, thick durable straw. Right out of the package it has no plastic smell or any other odor, which means VOC free materials. This cup is absolutely neutral.Second, the lid is tight fitting and well sealed. There's a gasket in the lid that keeps fluids in and the only place it can really leak is the hole through which the straw exits. Even given that, if you tip it over that hole is tight enough that the fluids don't gush out, just drip. If you pick it up right away you won't have much of a mess at all.Last, did I mention it's inexpensive?I use the cup exclusively around my office, it never leaves the building so temperature differences aren't a problem for me. The sleeve on the cup is thick enough to keep my fingers from freezing when I've got ice in the cup, and it gives a great non-slip grip. The stirring "fins" on the straw are a little bit gimmicky I guess but they at least serve the purpose of keeping the straw from pulling through the lid. The only tiny think that bothered me about the cup was it took a few tries to get used to lining up the threads to close it. For some reason the first couple attempts didn't close just right and when I tipped the cup to drink it leaked a little. It's not in any way a defect in the cup, just me not paying attention to what I'm doing.Need a cheap, durable, quality cup for use around the office/home? This is the one to get, hands down.

I have been using this cup constantly for two days now. There are many things I love about it:It holds a lot. I want more than 12 or 16 oz, especially because my kids both want to drink from my glass.It's sturdy. I can fill it up all the way and it feels solidIt has a great straw. My daughter will sometimes bite down on a straw which crushes it and drives me nuts. this straw is nice and thick walled. It also doesn't have that weird plasticy taste.It's wide enough to hand wash with a sponge. I like the insulated mugs but I often can't get my hand inside them with a sponge because they are too narrow. This is easy to clean.The straw doesn't pull out but is removable for cleaning. The straw is wide at the bottom so my kids can't yank it out through the top.The one drawback: it sweats. I like coasters, so this isn't a huge deal for me but it may be for you.All in all, I like this much better than the alladin cup I ordered at the same time. I'll probably order a second to have a rotation.

Love it. Does a great job one iced coffee and iced teas. Grip works well and the bottom fins on the straw are great for keeping it inside so you don't lose it. Seals tight and won't leak all that much if it tips over, just make sure to put it back upright so the liquids don't leak out of the straw if its on its side.Just something to be aware of, on hot and humid days, condensation will be an issue. This is not a double-walled or insulated tumbler so if you pack it with your favorite ice cold beverage and take it in the car or wherever, just be sure to put a napkin down because it will "sweat" in your cupholder or on your desk.Otherwise its a great tumbler and worth the investment.

Love these for ice coffee! The agitator on the straw keeps it from falling out which is lovely. I have knocked over my tumbler many times, and been thankful of the tight lid preventing a spill. I do notice some times that liquid will escape through the straw hole or near the seal and then I end up with coffee dribbles on my shirt. Just be aware. Otherwise the seal is tight enough.I wish that Copco would sell the lids and straws separately, as I have lost either in the past and don't necessarily want to buy a whole new cup. To me the whole point of buying a reusable tumbler is that it's better for the environment. Continuing to have to buy a whole new mug each time, negates that good purchase.

I didn’t expect much, but this is a surprisingly great cup! It withstands drops on its side with barely a splash, no leaks around the rim, no condensation, easy to carry, and I’m really surprised how useful that flair is at the bottom of the straw! Can stand up straight with the lid on it while refilling, or work to stir powders or anything that may have sank to the bottoms.

At this price, this Tumbler should be thermal! However,I am not impressed at all.I suppose it is ok if you don't mind one that sweats all over your furniture. It is flimsy thin. I would imagine these cost about a quarter each to make in that Chinese factory. I do not recommend these Tumblers unless you don't mind sweat on the outside that eventually drips down to form a puddle. They do not compare at all to the Aladdin thermal tumblers I ordered from Amazon before at about the same price, the only thing about the Aladdins is the straw is larger than a normal straw. I'm keeping these only because I need them for Christmas guest.Make sure you have something to put between them and the table you are sitting them on.Pros- Nice to look at, Doesn't spill contents with the lid on,Comes with it's own straw that is the size of a regular straw. The straw won't slip out causing spillage if a child gets hold of it.Cons - Thin, would not hold up to dishwasher washing so make sure you wash by hand, not insulated, sweats profusely on the outside causing water to drip down the outside like a regular glass you can buy for a buck at the dollar store, way overpriced
