Last as long as branded at 15% of the cost
I'm not sure how I missed the fact that these were available in generic form. I have been an Oral B user forever but only found the cheap heads 2 years ago. This particular iteration is absolutely the best style for full mouth coverage. I have always surmised that they only included the round heads with the initial base purchase so that people would rush out to buy these double heads from them - which is where I assume they make their most money.
