Color Me Impressed

I'm not easy to impress, most of my friends know that. This, though, is an exception. I've never had long-haired dogs before and since the boys came along, my house is about 4x more dusty (let alone, hairier) than I've ever experienced. Came across this as I Googled about keeping the dust down. Went from needing to dust AT LEAST 2x week, to every 2-3 weeks in the bedroom. Same thing with vacuuming. Even today, while dusting and changing the bed, it was "just" visible....and it's been 2.5 weeks. Highly recommend! I bought 2 and now trying to figure out where to put the other one. Color me impressed.
