4.5 stars
I was going to rate this as 4 stars since I had to cut down each invidual replacement so they would fit in my standard curler. They are about 1/5 inch too long. However, I am changing this to 5 stars since they (accidentally?) gave me 3 more than their ad stated, and the silicone is holding up very well. I'm still only on my first one, and don't see a need to replace it any time soon. This package will last me a VERY long time.
Rating: 5 stars
