I looked at many replacement toothbrush heads for my Plaque series toothbrush on the Groupon website. I was a little worried because most of the reviews were not favorable (low quality, didn't fit, etc) on most of the replacement brushes. However, this particular replacement pack did receive higher reviews and I couldn't agree more!!
These replacement brushes are of high quality, fit perfectly and even come with their own covers.I would highly recommend them!
