Replacement for Grundfos valve
This is to replace the original Grundfos valve, which runs over $70, which one was much cheaper. I inspected it closely, abnd I found it to be built identically to the Grundfos one. I felt confident it was a good choice.I tested it by closing the cold valve, and seeing hot water flow out through the cold tap. Works fine. And it does shut off fully. The old valve failed 'open', not shutting off, and also failed to close, not shutting off when the temp was reached. This happens because the valve gets covered in limescale, and it can be cleaned by soaking in vinegar. In this case, I just decided to go with the new one, which works great. I;m sure it will last as long as the Grundfos one, but with hard water, it will be necessary to inspect it and clean it with vinegar once in a few years.RECOMMENDED.

Good standby/replacement or for adding another zone
I initially got this bypass valve to add another instant hot water zone on my house. My new tankless water heater has a built-in recirculating pump that can use either a dedicated return line or the cold water line, and it's in the latter configuration that I'm using these valves.This one appears to be a direct copy of the Grundfos bypass valve that came with the water heater... it should fit as a direct replacement. For now I'm holding it in reserve as a backup. The original one came with the extra hoses and adapters needed for installation and this one didn't. That's a good chunk of the cost difference if you're not replacing, but adding a new one.Overall, we're not convinced that using the cold water return is the best option for us, since we don't like the warm (or hot) water coming out of the cold side of the faucet. For that reason, I've paused expansion of my installation to other faucets for the time being.

Works Great
Great do-it-yourself project. Plumber wanted over $500 for parts and labor. I installed it for $40 in 15 minutes. Do not try if you are not familiar with fixing any plumbing.

quiet and works well
So far this valve is very quiet and working well. It replaced a stainless steel valve that made all sorts of noise.
