Review on 2 Sets Flexible Kitchen Tap Head Faucet Sprayer with 360 Degree Rotatable Water Spray - Universal Adapter, Sink Accessories Tools by Alif Eagle

The top connector is plastic. It doesn't have enough threads to hold the faucet, only 2.5 threads on the connector. It often shows up when the pressure rises. I couldn't use the included filter or rubber grommet because there wasn't enough thread to hold this thing to the faucet. I had to use tape to keep it from coming loose. In the end it failed because the water seeped through the glue. If you rotate it more than 30 degrees, the seal will leak out at the top and splatter on your face and chest. Look for something better. It's not worth the money or the hassle.
