Work far better than the brand name brush head; needs a cap included.
Wow - I got fed up with the brand name brush I was using after a bad checkup where I was told I had an uncharacteristically high amount of plaque buildup.  These work sooo much better - they're the only option I have for a compact brush that fits the base I use, and they are outstanding.  I just with the manufacturer/seller would offer a cap.  It wouldn't need to be for each brush, either - just one per package of four.  I'd gladly pay a bit more to have that option.  If a cap were included, this would be a five-star rating.
