Review (4/5): Wish they'd come with plastic shields.
These manage to be very generic looking. Which is fine, but interesting that I could notice considering it's just a toothbrush head. They just don't have the decorative banding on them that some of the others have (they do have the color band for distinguishing between multiple users). What I don't like is that they do not have the plastic shields with them, although even the originals don't have that anymore. As my remaining shield gets cracked further and further, I wonder how I will continue to travel with my brush.
These seem basically the same as the originals. It's sort of hard to say if my perception that they are just a tad less good is based on something substantial or just aesthetics and packaging. If the price is right, they're worth a try.
