Here are some easy fixes. 1. Make the install book complete. More diagrams. More installation tips. More operation directions. A check off list of what needs to be looked at before you move it in to the test place because you can't reach it after. 2. Those little red switch hoses need to be a bit longer and better clamped on. 3. The Gel Coat filler plates for the end of the tub should be attachable once the tub is in. Clips would be great. 4. Stick the model and serial number in the paper work so we can register these easier. 5. Where's the drink holder and fake claw feet?
