Customer Project Review

“Hi Gene, I wanted to let you know that your instructions for a DIY hot tub were fantastic.  I referred to the video and booklet throughout the project.  As a one-man labor force, and with limited spare time, the project took me a bit longer than expected, but turned out real nice, mostly because of your detailed instructions.  Each decking panel is removable to allow access to equipment.  Now I’m just waiting for my new cover to arrive. Thanks Again!”
