This is my first post as an "Official Sponsor" on this forum. I'm the lawn care professional that invented the "Sprinkler Buddy". The Sprinkler Buddy custom fits lawn sprinkler head Rotors and Spray Heads unlike any other similar product found on the market today. They have the highest UV protection and are Made in USA, Florida. If anyone should have any questions after visiting my website @ http://www.sprinklerbuddy.com please ask them here publicly or if you prefer privately, I can be contacted through my website "Contact Page". I'll get back to you ASAP either way. Thank You for your support.
