Review by Anonymous on 8/4

We've been using various Thermos Funtainer/Foogo bottles since they came out with them 7 or so years ago. The only complaints I have is the bottoms have on occasion come off and I would not consider them "leak proof" since they do tend to pop open in the lunch bag when the button gets hit. For this reason we switched our water bottle for the school year to a plastic one :-( because it has a flip top lid that locks. I really wish Thermos would come up with this feature.

We have been using these since August for lunch and after school snack time. I love that I can send quality milk in them and it stays cold (with milk ice cubes) throughout the day. We have had to replace the straws, as my 6YO chews through them. They were $1.50 from the Thermos company. Otherwise, no complaints, I think they are great for the price. Ordering more for Easter Baskets.

These are impossible to find in any store. I did find the decorative ones but they aren't dishwasher friendly. The decals wash off and look junky. I got the solid ones to avoid this issue again. These are great for school days. The beverage stays cold all day!

They are working pretty well, but where do I get replacement straws? I have searched your website?

Review by Sheri Martinelli on 4/29

Looks nice, seems watertight so far, and remains cold. Only concern is the way the rubber straw is bent in half by a pretty sharp piece of plastic in order to fit when the top snaps shut. Seems like a design flaw to me. I think they could have come up with a better system. It seems like it will shorten the life of the straw.

Usually the Mighty Nest products are great but this one leaked. Will try to return this product...

Thank you for writing a review. We're sorry to hear that this bottle leaked for you. A few tips to ensure that it's 100% leak-proof: After washing the components, make sure the straw is pushed through the bottom of the lid completely with your thumbs. Also, the lid must be in its closed and locked position. If you're still experiencing an issue, please contact us at or 847-905-0567. We appreciate your feedback.
