Review on 🦷 8 Pack BrightDeal Toothbrush Heads for Philips Sonicare ProtectiveClean 4100 5100 6100 DailyClean Plaque Control Gum Health G2 C2 Toothbrush Head HX6817/01 HX6857/11 Electric Toothbrushes by Richard Messar

Good price, fast delivery, fits my series 2 toothbrush and works just like my original brush head. There seems to be a gap in my toothbrush, but don't worry, everything is fine. There's room for one of those plastic rings that tell you whose toothbrush it is. I don't wear them so a slight gap is visible but there is no difference in performance. We love them and especially love that they come with six heads - five doesn't work in a two toothbrush family, and who wants to order more while one just sits there?
