Product review (5 stars): Simple, reasonably priced, and got the job done.
Very simple, but just right. Long and sturdy wooden handle and two different diameters of bristles make the job of cleaning under the fridge less of a hassle. I was able to clean all around the refrigerator compressor and get the caked dust out of there. Most of the dust fell to the floor, which I vacuumed after. I hosed the brush off later to clean the bristles. Probably not something you would use too often, but when you need it, it's nice to have the right tool.
