My partner and I commute to work and carry our small daughter to nursery on our bikes. With the increased volume of cyclist casualties this year I'm not content with just the normal set of lights, etc. I want to be lit up like a Christmas tree this winter! So I got these alongside other reflective stickers and some valve-cap lights. They are well made and you get enough to distribute them generously across both wheels. I felt they were a little overpriced at the time, but they've since come down in cost and after all, £8 isn't much to help stay alive and healthy. As another reviewer says they aren't a replacement for a good set of lights, but they're a good addition and I would definitely recommend them.
