Review on IRON °FLASK Rover Tumbler TR_32DarkNight by Francisco Yim

I haven't used the keep warm function on this product so I gave it an X rating but it keeps cold well. Im impressed how leak proof it is, when closed I almost threw it on the floor because I accidentally hit it with my hand trying to pick it up and it still hasn't opened. You have to be careful not to over fill because what you may think is the fill line, I'm not sure as I filled too close to it and the liquid spilled out when unscrewing the cap. I don't actually use a straw because I close it so often because of the tightness, awkwardness (see: almost throwing it across the room, just for distraction) and the baby running with the animals. If a straw is important to you I would choose one with a hole at the top because I've had drips like this and the plastic ring that keeps the straw from falling out helped prevent most leaks but this one would leave MASS. . There are also many beautiful color options! I wasn't sure which mug to buy after seeing so many on the market at different prices, but I'm glad I bought this one. While it's not inconvenient for you to have a larger mug due to a drink holder or some other reason, you're paying a few bucks for almost double that I think.
