I had a very bad experience on this product.  I order this item with a tub on 7/11/2017, the product arrived 7/17/2017.  But I have to wait for my tub to arrive to install it.   Middle of October, my tub arrived and my contractor install this item.  The Faucet failed right away.  The main spout worked OK, but once you switch to the hand held spray, the connector between the spray and the post popped out and water is prayed all over the place.  We are forced to shut it down.  Called for help but got nowhere.  Tried to order another one to compare, but it is out of stock until 10/15/2017.  Don't know what to do now.....
I suspect this is a damaged product design to begin with and the saler just wanted to sump it on the internet.  Bad, bad, bad....
