Has protected the bottle really well from shocks and bumps. In addition, it reduces the noise when handling the bottle. There is a small hole in the bottom, through which any liquid that may have entered will come out. Has stayed in the bottle really well and has never accidentally come off. In my opinion, an absolute accessory for a Hydro Flask bottle.
Protects the base well and holds it in place where it will be placed.
Good, the bottom is not scratched and the bottle stays on a slippery surface.
