Most of them were great
I bought these for the variety of colors and the kids loved the colors! Some adults in the office wanted one too. The hand sanitizer we had was pretty liquidy and the bottles did not leak while we had them. I haven't gotten negative feedback. However, I was grateful that we didn't have 36 kids come through our Blessing of the Backpacks line because about five had malformed plastic. It almost looked like they had been somewhere hot and melted into strange shapes. I vacillated between 3 and 4 stars, but I couldn't give a 4 star review when I would have been embarrassed to give away some of these because of how poorly they fit in the silicone holder after being misshapen. If you don't plan on needing all 36 and want colors, then I think it is still a decent buy.
