Example Input: After having this on my lips for 20 minutes they started tingling in a way that reminded me of an old plumbing lip gloss I had long ago. My lips definitely felt more swollen afterward, however I suspect the only one who could notice a difference was me.
Example Output: 3

Example Input: Fit exactly as expected, works great. This was a replacement for the OEM seat clip that somehow became separated and lost while cleaning the car seat. No issues at all.
Example Output: 5
