Etoto 580ML Plastic grenade bike water bottle, food grade silicone stretchable cycling sports water bottle, funny foldable water bottle (Green)

My son wanted this bottle and I was very skeptical about it but I got anyway. I was impressed with it. It looks great 👍

This is a very fun water bottle. My 6yo son loves it, and I am fairly impressed with this product. The food grade silicone is very flexible and the cap when fully seated does not leak. The reason it does not leak is due to the slightly angled silicon seal that does not have any separation seam in it. Meaning the seal is 100% all the way around the cap and is one piece.I am a Professional Mechanical Engineer, and the material of the body is what I like about this water bottle. The material of this bottle is not tin, stainless steel, high-density polyethylene, and it is not polyethylene terephthalate. It is basic food grade silicone. The about this item states: “The temperature resistance is from -40 ° C to 230 ° C.” This is a great lightweight bottle that can endure some punishment. And over the years we have been through all of those mentioned materials for both of my kids water bottles, and they just do not last.When closed the spout makes this bottle airtight. And you can easily test that because you cannot expand or collapse this bottle unless the spout is completely open. And that equates to a leak proof spout. Collapsed, it holds a lot of water, but fully expanded… 580ml equals about 19.6 oz of fluid, which is more than enough to hold a standard 12oz bottle of water.And why not have fun with the design… Which is why my son has this attached to his backpack.

First thing is the box was damaged it came in as it was only in a heavy envelope which was smashed. Has a funny feel to the item itself, so it's not at all what I expected . Good thing it's for a young boy as a Xmas gift, or I would send back

This ZDBOTTLE-grey 580ML Plastic Grenade Bike Water Bottle is perfect for my travel backpack. I won't be collapsing it though when going through TSA at the airport so it's going to be fully extended. However, when I'm out and about somewhere else, I could actually collapse it down when it's emptied. It's lightweight and functional for what I need it for plus it's not oversized for travel. Bonus point for being just the right size for my needs and the cool form factor. One thing of note is that it could be slightly difficult to handle when partially empty because it collapses unlike regular hard-side water bottles; however, thanks to ridges that's part of the design, it's actually manageable. In fact, better than my other collapsing water bottle but then again, that comes with the collapsible design.At $11.99 when I got it, it's a good deal considering the cost and usability.

Cheap and wouldn’t even hold an entire bottle of water. More trouble taking the time to put anything in it than it’s worth,
