I've compared them to much more expensive products I've bought from my local supermarket here in America and they appear to be a legitimate substitute for Oral B . The only thing that is unusual is that most of the language on the packaging is written not only in English but also in Polish. My guess is that they sell them at a lower premium in Europe than they do in America (the retail price for them in the US is ridiculous), but that's just a guess. I've been using one for a few weeks and it works and cleans just like the ones I bought at the store.
