Review on Steel Double Wall Vacuum Insulated Water Bottle with Rechargeable Bluetooth Speaker - Premium Design + Lights, Convenient Drinking Spout, Lid Lock, and Carry Handle - 700ml/23.6 oz - Blue by Grant Galloway

First of all it's big. 12 inches high and nearly 3 1/8 inches in diameter. It was almost too thick to fit in my bike bottle holder, but I was able to bend the holder and fit in there. Very nice lid that opens with a button and closes tightly when closed. And it's a double-walled thermos that holds the temperature really well. The bluetooth speaker is what they saved money on. It fits easily, but I can barely hear it when riding my bike and the sound is very "thin". I would probably get the same or better sound out of the speaker on the bottom of my phone. So overall I'd say this is a good buy for the bottle alone, but don't expect much from a speaker.
