Ordered two sets of doors, one for tub and one for shower.  The tub was the first to be installed, but one of the mounting brackets for the top rail was defective/wrong... too thick to fit over the bar.  I pillaged one from the shower set - worked great, installed in a few hours and the doors are beautiful!  Contacted Vigo customer service regarding the bad part, had a reply within an hour asking for a copy of the invoice.  Sent off the invoice and had shipment confirmation within minutes, correct replacement part arrived two days later.
