Had this installed by a plumber and after the install a leak started to form by the knob to turn the water on and off. Contacted wayfair about the issue, but was told to contact the company directly. Contacting the company is a pain, they never answer the phone and messages are left unanswered. When you finally get someone to answer they give you the runaround and tell you to contact someone else in the company. Looks like they are selling junk.
