We've worked with Herman Fu on six projects so far. He has been exceptional every time. Clients always rave about his professionalism and they all say that he is the ultimate gentleman. The product has always been installed on time, perfectly, and exactly as promised. His pricing is unbeatable too. Highly recommended!

If you are planning to order doors or windows for your clients from Corona, think twice. We ordered some custom products for a custom residential project. We were promised installation in 6-8 weeks. At 9 weeks, our client still had no delivery. Many calls and messages to Tony at Corona went unanswered. At week 10 we finally got a hold of Tony who promised that the order will be ready for installation in 2 weeks because they are waiting for the special order glass. He promised! Week 14, I returned from vacation and still no delivery. Employees at my office tried several times to get a hold of Tony, but had no result. Finally, I was able to get a hold of him on week 15. He promised that the order is at the paint shop and will be installed on a wednesday, week 15. We called tuesday to ensure that the order will be installed and after many attempts, we finally got an answer from Tony who promised that everything is on schedule for wednesday. Our client waited at home all day wednesday and still no delivery. After trying many times, we finally got a hold of Tony. Finally our order was delivered and was installed next day on thursday. At 7pm, we received a call from a concerned and furious client who was complaining about the installation quality. Over 7 weeks' delay, lack of professionalism, and poor finish are all recepies for disaster. Obviously, our relationship with our client was destroyed beyond repair and we looked like fools for hiring a deadbeat company. Beware, beware, beware... In all firness, Corona's product was built well, but after 15 weeks of waiting, no one cared or appreciated!

We purchased a kitchen from Norma priced at $50,000. A few months ago we required warranty service from Dunbar & Ross as parts of the kitchen began falling apart. When we called Norma for support she was very cold, crude, and uninterested. She ordered the parts we needed but said that they will only give us the part and installation is up to us because their installer is too busy. When the part finally arrived, it did not fit. We tried calling Norma who did not return our calls. At one point an employee of Dunbar & Ross actually hung up on us. All of this hassle is absolutely unacceptable. We will NEVER AGAIN recommend Dunbar & Ross to anybody after being treated this way. To this date, our problem remains unresolved and no one, including the manufacturer has returned our numerous phone calls.
