This is my first time to install this frameless shower door myself. It is not difficult to install. The manual instructions was confuse but I had to spend more time to figure out. Everything was good. Only one thing I did not satified was a threshold piece at the bottom of a door is too low. If I take a longer shower the water will leak out at the bottom. The water seal came with a door did help to stop a leak. I have to purchase a other bottom seal to replace it to stop the leak. Other then that I was very happy with Vigo product.
