"Today I called 815-576-5700 with questions about which replacement wall switch timer would be best to replace my dead timer. I spoke with what sounded like a middle-aged guy, didn't catch his name, but he was wonderful. He asked for the model number of the old timer. I didn't know, but I told him it took an AA battery and now it read "NOOP" and didn't work with a fresh battery either. He immediately knew the model number and which model I should replace it with. He was amazing. I told him I wished the guy at Lowe's had been half as knowledgeable as him. He told me he worked at Motorola for 20 years before working for you. You need to keep this guy as long as possible, and make sure he trains others to provide such excellent customer service. I have never spoken with any customer service rep as well-informed about their products as this man. Track him down and give him a huge raise!!"

"Just a short note to say I love your products. I replaced the wall switch for my front porch light at my very first apartment back in '72 so the light would be on when I came home from work. When I moved, I removed that in-wall timer and installed it at my next apartment....and the next. (Thank goodness my beloved Dad taught his daughters some basics about wiring and electricity.) I gave one to my sister and helped her install it back then, too, and she's still using that same old-model at her home.

When I got married and we moved into our first "real house" we installed more timers and we continue to use them to give outside light after darkness and also to give that "lived-in" look on interior ceiling lights when we are traveling. Over the years the products got more sophisticated and in some ways more complicated, but they have always been dependable. I like the battery backup for remembering the programs even when the electricity fails...that continues to be one of your best improvements in my opinion."

"Wow--quick and super service!! What an outstanding combination!! I am impressed as we seem to be in the age of dying customer service--your response definitely encourages my repeat business!! Thanks for caring!!

I am using the timer as we have a rash of home invasions--in the night when people are in their homes sleeping so you are a 'life saver' too!"
