I am very grateful to Marty for his willingness to be available to troubleshoot my T-24 timer on a Sunday night!! I posted my question and didn't expect a reply until Monday, so didn't see it until after dinner. He was right there to respond, even at the late hour. Remarkable commitment to customer service! The glitch turned out to be in my reading comprehension, and my mister is working beautifully. Great product! Thanks, Marty, for your support!
