This thing has proven to be the worse I have ever purchased.  I have a second installer coming out this week to try and repair it.  The shower faucet leaks profusely when I am trying to fill the tub.  I went out and bought a new universal valve and it still doesn't work right.  I called Wayfair and they patched me through to a hostile Delta representative, the seed of Satan and nasty.  She was as rude as anyone could manage to be over the phone.  The only missing element was an eye role.  I wish I had not bought this thing.  I would not recommend this product to anyone.  I had to replace this faucet in June 2020.  It's not worth the money.
