Works fine
I was looking for a toothbrush head replacement for my ibrush.  The price for those were $19.99.  Searching for an alternative I came across Bestek and saw that people used them as a replacement for ibrush.  We bought them and they were just fine.  They look the same, they work the same and they cost less per package.  I will be buying these as long as they are cheaper than the name brand.  UPDATE:  No longer available, and I don't know of an alternative.
