So far I am very pleased with this purchase!!  Easy to install however I did need to purchase a water connect hose as this toilet hose is not standard size, just a little bit smaller, no big deal!  Our hardware store was johnny on the spot with correct hose size.  
I can’t say enough positive good stuff about Wayfair!  Becoming my favorite online shopping place, this shipped very quick and I live in the mountains in the middle of 
nowhere.  Kudos to Wayfair!
