Product review (5 stars): Cleans hard to reach areas with ease
This is the perfect brush for all refrigerated coils.  I ordered many different sizes because this one wasn't immediately available.  This was the only one that was able to clean all the coils.  The fibers have just enough "give" to get into small spaces and do the job.  The other brushes were either to stiff or too bulky.  This is the one you want.  It was worth the wait and did a better job.
