My rating is based on his quickness to respond to the initial call, setting up a meeting within 3 hours, knowledgeable about product, installation and eagerness to meet any and all condo association stipulations. Last but not least he said he has a one year price but gave his BEST price upfront so there was no haggling necessary. Finally NO money until job installation 100 pct. completed to out satisfaction. What else can you ask for?
