Best with caveats
First the negatives:
1. It will likely scuff your water bottle, be it plastic or metal.
2. It probably will not work as an under-downtube cage, particularly with 2x/3x front chainrings. 1x will probably work.
The positives:
1: It's steel; it's bendable, and will hold your bottle securely. On gravel and rough paved roads, this feature ensures you arrive with your fluids. You probably won't need to bring a separate strap to keep your bottle in the cage.
2. It has multiple mounting holes to mount with to get the proper positioning on your frame and/or to make it possible to fit your bottle within the cage on your frame.
3. It fits most common 32-40oz water bottles made of plastic and/or metal. I've personally used it with Nalgene (32 & 48oz), Hydroflask (40oz), and CamelBak (32oz) water bottles. They all fit. They do have scuffs, but they fit.
