Review on Davis AirFlow Tels+ by Mario Madden

They work well. Make sure you paste it where you want it the first time. Repositioning is not a good idea. I installed them on my mainsail and turned the Genoese staysail. I basically guessed where the best place to install them is. It would be nice to have some accommodation suggestions. As an advanced sailor, it would be nice to have a little less guesswork. They are easy to assemble and seem to be holding up very well. (I cleaned the surface of the sail before gluing, which I highly recommend.)
