I also have. It makes a lot of difference and is good fun to install. As 2012 says above, just take your time. Don't do it on a hot day, as it seems to make the adhesive set quicker.
The other (minor) issues I have with it is that you have to be careful when you wash the bike, as it is easy to pull up some of the edges. Wax can also highlight the edges (you just have to remove the residual wax carefully with a micro-fibre cloth after waxing).
Plus, I keep spotting some tiny bubbles that I missed during the install. Very powerful lighting is recommended to minimise this.
