This product is well designed and was an easy to moderate DIY install.  My wife and I tag teamed this product on the installation and after SHE read the instructions we were able to fairly quickly.  The instructions are written in a way that they are understandable, although it could take some re-reading and study of the pictures but it is totally doable for the average DIY enthusiast.  Not only are the instructions relatively easy to understand, but they lay out the tools that will be need so that you can collect them prior to starting the install.  The product is working as I had expected it to once the calk set up.  Keeping water in the shower area as expected.
