Great quality and great price
Looks and works exactly like the ones at my local big box store, at half the price. Solid brass construction should last a long time.

Not only did it arrive used, it doesn't work.
Valve arrived in dirty packaging, with Teflon tape inside the threads. Also it doesn't make a perfect seal internally making this 100% useless. Buyer beware! Shop elsewhere!

Do not buy.
Low quality coupling. Installed three times, leaked every time. Had to purchase a lead free coupling locally. Save your money and frustration; not worth it.
