Review (3/5): Works fine, overpriced.
The product works well and allows you to comb out carpet fringes very neatly. I would have liked a longer handle, but that is just a matter of preference.
My reason for three stars is because the rake is really overpriced. It is basically a few pieces of dowel glued and screwed together. Anyone with the inclination could easily fashion one from 5/8" dowel bought at a hardware store using the ends of chopsticks or wooden meat skewers for the comb's teeth! All you'd need is a drill, a saw and some glue!
The high price is presumably because the rake is made in Germany--and perhaps also because such rakes are not easy to find. Let's hope the quality matches the price and the rake proves to be durable. I'll let you know.
