Pack of 4 heads, great price, cheaper than the pack of 2!!! Had a good look around as I just bought the Amazon deal on the rechargable toothbrush.
Online as well.
Suitable for Triumph
Our power toothbrush range is backed by over 60 published clinical studies that demonstrate the superior performance of our oscillating-rotating technology. The EB17 fits on all Braun Oral-B power toothbrushes. While the new brushhead has been designed to enhance the 3D Excel technology, the EB17 fits all existing power toothbrush models. The key features are the FlexiSoft bristles, which bend when wet, allowing the longer Interdental Tip bristles to reach between teeth. All Oral-B power brushheads are based on the compact rotary design pioneered by Oral-B. They all have soft end-rounded bristles and are clinically proven safe on teeth and gums.
