Product review (5 stars): Nice and flexible
Not much to say about this simple product other than the fact it gets into hard to reach areas and gets the job done.  The wand is a semi flexible wire that can reach around things but not so flexible to bend 90 degrees.  It's a little stiffer than a wire hangar.  The important thing is to clean around the coils of your refrigerator and inside your dryer. Keep your shop vac near to suck in the dust that is loosened by the brush.  Keeping your coils clean will improve the performance of your appliances and save electricity.  Just turn off your appliance before poking around and wear a dust mask.
