Review on Midnight Blue 32-Ounce Aquatix Flip Top Stainless Steel Sports Water Bottle - Double Wall Insulated by Kenneth Harris

I've been using this for about a month now. Works great as a thermos. The interior is made of stainless steel and still holds up and the lid closes tightly so it doesn't leak. Good durable powder coating on the outside. Two things to note: 1) Since it's not plastic, it's quite heavy. Especially when it's filled with 32 ounces of water, so keep that in mind. 2) The locking mechanism on the lid wants to move to the locked position automatically when you close the lid. Not sure if that's on purpose, but every time you open the lid you have to lift the latch. It was unusual at first, but I got used to it.
