Installed my smart buddie and it was pretty straight forward following along with the aquatic life classic ro system video. My only concern during installation was when I pushed the ro tubing into the smart buddie, the face plate that the line connections are on would depress too. It just made me a bit nervous that I would break something. Other than that, this is an awesome unit. Im making water so fast now and seeing 88-90 psi. My tds after the membrane is now 1 whereas my previous best was 3 tds after the membrane. If you don't have one, get one!
