Review on Genkent Replacement Brush Heads: 20-Pack Compatible with Oral-B Sensitive Care Electric Toothbrush by Dianne Williams

They don't last as long as OEM brush heads, but I still change brush heads for toothbrushes quite often. They do the same job as the official Oral-B products, although advertising says they clean "500%" more. They also cost 500% more. Like printer manufacturers, who make most of their money from ink/toners and not the printers themselves, Oral B makes money selling toothbrush heads, not the toothbrushes themselves. If you don't have much disposable income and don't invest in Oral B, buy They universal heads instead.
