I just wanted you to know I am very pleased with my lanai windows. I think the windows are good looking, and both the glass and screen panels move smoothly and effortlessly. I also want to compliment the two men who did the installment. They were very professional. They arrived when they said they would, they knew what equipment they would need and brought everything up front and thus didn't need to keep running to their truck for additional equipment. They worked well with each other, knew what was needed and worked with little if any wasted time. Both men showed pride in their work, and the result is evident in the final product. Thank you again for everything.
