JIUWU RO Water Feed Adapter Valve (1/2 to 1/4in)

I bought this to replace the cheap valve that was included in an RO filtration system. This one seems to be much better constructed, and after spending hours trying to get the old one to connect without leaking, once this arrived, I had it installed and working in less than 5 minutes. I recommend this product!

Item not as described. The "tap" only works to turn the small attachment on and off, the other parts go right through and the sizing is wrong, we need to buy yet another piece to actually make it fit the faucet AND a cap for one side to try and work around the useless tap. Not happyAlso does not come with plumbers tape as indicated in the photo

Great thanks

I like the fact that it is NOT a Saddle Valve. Pretty much all water filter/refrigerator ice maker water line kits (including the one that I ordered from Amazon) include a Saddle Valve. So why would you buy another water valve? Actually there are many compelling reasons.• In my case, I am a renter and I would have to opened up the wall under the sink to access the copper water pipe because the cold water supply valve is flush with the wall.• I was uncomfortable with the idea of piercing the cold water pipe anyway. Just seems like it is inviting a water leak/flood and the attendant water damage with possible mold/fungus requiring professional "remediation".• What I wasn't aware of, is that with a zinc coated steel clamp and brass valve body along with the copper water pipe a physical/chemical reaction called "electrolysis" causes the copper water pipe to corrode from a kind of "green cancer". Even if you didn't experience a leak at the time of installation, eventually a leak is guaranteed!• I also didn't know that Saddle Valves are a violation of the Plumbing Code in most states and that will hold up your building/remodel permit in most municipalities.

Fitted as a go between my bath, RO unit and shower. But unfortunately when on the RO setting, the shower is still on, causing extra water loss. So over all a bit useless.
