What people are saying about Wattson Classic

“Wattson looks good and is the kind of thing people want to have on display, which means they show their friends and generate word-of-mouth sales for installers. It’s a lifestyle gadget rather than a boring display.”

Kevin Heath

“I would be lost without my Wattson, even my kids are on alert for that red light.”


“The new software has made my Wattson even easier to use! I’m very pleased.”

Nick Andrews
