2 out of 6 leaked
I bought them 1.5months ago, to use with hand sanitizer for the kids' backpacks and my purse. 2 of the 6 bottles leaked all over (I checked, the caps were properly closed) so only 4 are actually usable.<br />The size is good because I don't have to refill them very often. The hanging mechanism is good, and I have had no issues with the carabiner nor the bottle breaking.  however only 4 out of 6 were good, so 3 stars.
