5 stars for 3 of the bottles; 1 star for the other 2 bottles
I was specifically looking for bottles to hang hand sanitizer outside of my bags.  These have carabiners that attach well to the bottles and hang with the lid facing downwards.  Two of the lids snap closed tightly, one lid is so-so but I think passable, but two lids open too easily.  I won't trust those two to not open easily and thus leak everywhere.  I did not need 5 bottles (but would have been nice!), so this met my purpose.  The two bottles that I am using work great without leakage.  But do consider that 2 of the 5 lids are not good lids when you consider the price ($12 for 3 bottles rather than for 5 bottles when I purchased.  I see that they are selling for $10 on amazon right now).
