Compatible Oral B Toothbrush Heads

Hi

I got these for my Oral B electric one. They work perfectly and I couldn't tell the difference.

Savers stock them.

Boots own brand

I used these before

There is any noticeable differences between the generic toothbrush heads. I bought this recently which is super cheap and looks okay. The official or expensive generics are nothing special from my experience.

Many thanks all
