This three way valve has been working great so far on my 05 Prius.The connector fit perfectly and all the mounts were good.I think a little more grease could have been used on the gears. (See pictures)It arrived in good condition.

Just want to preface this with the fact that this hasn't been installed yet.With that said, we have owned two gen 2s, and each has had this part replaced quite a few times. Enough so for me to be able to identify and test whether one of these is going to be worth the hassle of installation.From my measurements, multimeter testing, and thorough inspection, this one passes my "good" test, and will be installed when the OEM on our current Gen 2 gives up the ghost (which I can tell it will soon).Out of the 7 of these I've ordered, and 4 installed, 2 have lasted longer than 3 months, with one still on our first Prius and functioning. This one matches that last one in all categories, and has my hopes high that it will be comparable.Comparing these 3rd party control valves to a new OEM model, I look for similar weight (indicating similar internals), where the low quality ones are significantly lighter (nearly 40%) and have a higher resistance when tested with a multimeter.The cheaper ones also have a much more plasticy feel to them with little heat dissipation properties, leading to premature failure at the most inconvenient times (like the time we were at the vet in the middle of Texas summer during peak covid and it died, basically shutting the whole car down
