THERMOS Foogo Vacuum Insulated Stainless Steel, Pink/Purple, 10 Oz

this cup is our favorite, but it wasn't until our son got a little older. we like it because it's not completely vacuum sealed to make it leak proof and, therefore, the liquid inside comes out a lot more easily. if you've tried drinking from a leak proof straw cup, you'll know and it takes a lot of energy to drink out of them. i found that my son drinks more and more easily from this cup than some of his other completely leak proof cups, and my theory is that the liquid comes out more easily. it has a tiny air hole on the top to let air in when you drink, which means if you tip over the cup while the top is open, liquid will spill. if the lid is closed, it is completely leak proof. often, i throw the (closed) cup in my bag and i've never had a leak.i think this is less of an issue if you have an older toddler who understands that you have to hold cups upright or they will spill. my son is 27 months and he gets that. we still have some spills but i'm ok with that if it means my son is drinking more milk. other leak proof cups also do leak if you put in cold liquids like milk or refrigerated juice as the liquid warms to room temperature, except those leak out the straw, and that is way more irritating for me than the foogo.we use both the stainless steel and plastic and we love them equally. the stainless keeps liquids cold for hours--really impressive. you just need to make sure the inside of the cup is cold before pouring in the cold liquid. the plastic one is great for everyday use. we've had one cup for about a year and added 3 more to the rotation. they all look new. none have broken so far. the silicone part of the straw does wear down, especially with kids chewing on them, but they don't wear down as quickly as some other popular straw cups. overall, this is a fantastic cup for toddlers!

What I like most about these thermos containers is that the liquid will stay cold for a long time. I haven’t tested exactly how long. But I live in Southern California and it can get very hot here. I will put water with ice in these and leave the house with the kids around 9 am and the water is still cold when we eat lunch around 1 pm. While I do not use this for milk or juice, I can see that these would work well to carry milk out of the house for later.They are easy to clean and I like they are not made of plastic. I believe the straw parts are silicone – this is great if your kids tend to chew on the straw like mine do. These are very durable. It is a little hard to take apart sometimes for cleaning, but once you get the hang of it it’s fine. This is dishwasher safe, although the cap would likely melt if it falls into the heating unit of your dishwasher.The top has three parts: the plastic lid, the straw that goes in your mouth and the long tube to reach for the liquid. My husband tends to forget to add the straw – and without it you cannot drink! This cup is very durable. It will leak if your child shakes it, holds it upside down and sometimes it may splash a drop when popped open. But because I use this for water it isn't a problem as it has not proved to be at all messy. But I would not recommend for younger toddlers that shake their cups. These Playtex PlayTime Straw Sippy Cup, Super Friends, 9 Ounce worked really well when my kids were younger.

After trying numerous kinds of kids bottles and sippy cups, these became the only ones we use.- Stainless steel is a big plus when you have to leave the water bottle in a hot car in Texas heat, because plastic will emit toxic materials under such high temp.- The insulation works perfectly, keeps the liquid hot or cold all day long.- The straws have two parts, a long plastic straw and a soft silicone spout. Both can be removed and cleaned using a STRAW CLEANING BRUSH (caps because some users reported mold issue in the spout, with a straw cleaning brush and air dry mold can definitely be prevented. We've had these bottles for two years, and no mold is growing).- As far as the leak, I've noticed that if the little PLASTIC RING under the lid is forgotten, then the bottle will leak. The plastic ring is not just a decoration. Otherwise it's 99% leak proof when the lid is closed tightly. Once in a while there's a bit water coming out, but not a big mess at all.- Most importantly the kids can drink out of these cups without putting in much effort, unlike a lot of the spill-proof sippy cups, which are nearly impossible to suck out of. I've tried some adult straw bottles and they are not even as good as this one. So this is definitely our favorite cup. Will buy the Thermo Funtainers for more storage.

I am not one to write a review unless I'm truly impressed by a product. I purchased this product in December 2016. It has been thrown, tossed, dropped, kicked and slammed on just about every surface imaginable. Despite challenges it has faced it has definitely held up its end of the bargain. The only thing I would complain about is that the bottom part became loose and eventually came off, but was super easy to glue back on. This was definitely due to rough handling. The lid has completely come off several times when it has been dropped on our tile floors but after countless reattachment still works like a charm. My little one was less than a year old when I purchased this originally.Pros: easy to clean, durable, keeps water cold in our desert heat, perfect size for little ones hands.Cons: when held upside down and shaken water will trickle out.
