I have his trickler on my V3 Autotrickler. It is better than the Autotrickler trickler. It works so good I see no reason the upgrade to the complete system.
I had a problem installing it. I sent him an email at night expecting to hear back from him rhe next day or so. He called me that night less than 30 minutes after I emailed him. We worked it out on the phone. The problem had nothing to do with his trickler.
