"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

"We went with Elizabeth Shutters because they are made in the USA and lead time was much less than anyone else. Cost was about in the middle of the others we received quotes on. We were very excited to get our shutters installed. Mike the installer was on time and professional. The issue is the actual quality of the shutters. We only had 5 windows done and every shutter has some type of mark from scratches, chips, gouges and even paint rolling down one. Most of the issues were on the frames but some on the actual shutters. We also were having a shade installed but the bracket was not correct. Things happen and I even understand some issues with product. My complaint is that I reached out to Elizabeth Shutters exactly 1 week ago today. Told them of the quality issues and sent pictures. Also commented that pictures are hard to see everything and I was hopeful someone would come out and look. I also asked when the bracket would be in for the shades. Again 1 week ago and I have heard nothing back. That is not acceptable."

"excellent work"
