Review on 💦 Sumnacon™ G1/2" Full Brass Shower Head Flow Control and Shut OFF Valve: Enhance Your Shower Experience with Precise Water Flow Management by David Jennings

Bought two to make a second shower head. And I got lucky because the first one licked out of the slot where the tongue grip moves. But the second works great, except it needs to be tightened hard to prevent dripping from the threads, even with teflon tape. The action is smooth and simple. It turns off completely. This saved me the trouble of tearing down a wall to replace old, leaky valve handles that don't fit modern washing machines. My rating would be 5 stars if one of the two wasn't defective. Revain returned the money quickly and I will order again. Looks and feels like a quality product.
