The product I have today is the Thermos stainless steel water bottle. It's a product that my daughter's been using for over a month now, and she really enjoys it. What I find is that the product's pretty sturdy. You can throw it in a lunchbox or in the school bag. It's waterproof, so even if it goes upside down, water wouldn't fall out of it. What's nice about it as well is that it keeps the liquid inside it cool, so if I want to use juice or water, cold water from the fridge, it'll stay cold for most of the day. It's easy to drink from. It's also really easy to clean. Everything pretty much comes apart, so it's easy to clean the rubber portion, all the inside, so you don't have liquids, juice, something like that staying in there and getting moldy over time. It's also fairly easy to put back together as well. Definitely something that I would recommend. It's a very good product and have no complaints so far.
