Review on Zefal Wiiz 2016 Side Mount Bottle Cage by Robert Long

Bought a thermos HS4080 24 oz. Water bottle, but the 3" diameter didn't fit my wire cage or any of the holders I tried at the bike shop. I chose the 170001 Zefal side-mount cage since one reviewer said its 24-ounce (also 3-inch diameter) bottle would fit Polar. Today I tried Zefal for the first time and it's fantastic. The thermos didn't move at all and was easy to put in and take out of the Zefal. The water thermos is large and heavy compared to a plastic bottle, but didn't move at all. The Zefal mount is slotted so the entire mount can be moved up or down to the optimal position. My regular sized bottle works great too, but I doubt I'll ever take this non-insulated bottle with me again. I'm a road rider so I have no idea what it would be like on a mountain bike.
