## Customer Reviews

### ⭐⭐⭐⭐⭐ Great quality and great price
*by S***W on July 11, 2024*

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.

### ⭐⭐⭐⭐⭐ Saving money's most important thing to me and I save money by buying it
*by T***G on August 31, 2024*

Work just fine no problems

### ⭐ Not only did it arrive used, it doesn't work.
*by K***Y on September 12, 2024*

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!
