Go by brands. Go by what ever. I'm curious to what you all hate and what you like. What's failing this year? For me I've seen a few Hunter 8 station DC Xcores die under warranty (2). On one of those warranty's same system a DC Irritrol died on me too. Not sure if they are related. On that site I should note a very serious power wire runs about 40' away from the mount. If things die again I'm going to be bullsh!t cause its a freebee community job. Also my tried and true wireless Irritrol rain sensors have been giving me some issues like I never have had. Seemingly on the few I got I couldn't transmit or receive through a concrete sill and pad of a garage. Godammit I tried like 3 of them all with the same result. I finally just hung it in a bad spot with good reception. Are there any Toro Reps on here that can weigh in? My Rainbird 5000's are holding up like a champ. Hunter PGV's might of had 1 be bad. Other wise still buying those by the cases. Hunter Pro-c's have been great except for having to pay Facking $5.00 for a remote port what a rip off. End rant.
