Does anybody own one? How do you like it? I have been checking into getting either a Perma-Green or a Z-Spray, as our fert & squirt accounts have grown a great deal. I want to have something in place going into next season and intend to purchase one or the other end of Jan. beginning of Feb. I stopped by both booths at the Louisville show, and so far have tried to contact Perma-Green several times by email with no response from them. I sent an email to Z-Spray and will see if I get a response by mid-week next. Just wondered if you folks that are running Z-Sprays have had any problems, how you like them, & customer service. P.S. hello Perma-Green if you are out there you really should check into your customer service dept. over 4 attempts to contact spanning a month long period and still no response? I'd hate to see you guys lose a sale because of that.
