I ordered this product because my neighbor has a similar one and I really liked his. After installation, I/we've HATED this product!!! When the faucet is turned on, whether hot or cold, it seems as though a valve or pump continuously and LOUDLY thumps AND the sprayer connection drips viciously!!! The sprayer handle works with NO thumping, but as soon as you go back to main faucet the thumping and dripping starts all over again! I will have to go to Lowe's and buy a replacement faucet and figure out how to send this product back...it DEFINITELY is NOT worth the money!
