Query: Great product that gets out tons of hair

I had several dog brushes that I used on my Chow Chow/ Collie mix, but no matter how many times I used them, I'd always end up with tons of hair still in my carpets. I bought the FURminator after my sister's recommendation (she's a professional dog groomer). The product works wonderfully. It's quick and easy, and gets out tons of hair with no pain to my dog. It's a good size for a medium dog (mine is 60 lbs), but for any bigger, I might go for the larger model.
