Cheaper is better!

Would Recommend

I bought a more expensive valve and installed it. It wouldn’t always stop running. So I bought this one which was half the price and installed it. It works every time, no problem.

Can't cancel locks box store pickup.

Would Recommend

The product was fine. I ordered one online and was not able to cancel the purchase. So it's at in the lock box until Lowe's decided I wasn't coming. This point I haven't gotten my refund.
