Review on 16 Variety Pack: Oral B Compatible Replacement Brush Heads - Precision, Floss, Cross, Whitening by Kristen Rohr

I haven't had enough time to try them on to test them for endurance, but from what I've seen and experienced these heads are virtually indistinguishable from the original heads that came with my Oral B. Electric and possibly a little better if anything with stubble results and feel - overall a good buy I'd recommend but I've only been using them for a week. I'm experimenting with different styles marked with a product ID but there are no written details on the box about their exact function but I'm sure they were detailed online when I bought them? They come in 4 packs of 4 different types which you may not need but all have different features and cost money compared to the OEM brand and price. Great product - great price!
