Review (1/5): 4 out of 5 bottles leak no matter how tight you screw the cap on
one bottle is great. the other 4 bottles leak when I squeeze them (you can hear air whistling in and out) even if I screw the cap on as tight as possible. plastic thickness is good and are squeezable to dispense hand sanitizer but not too soft
Edit: I requested a replacement set from Amazon and again, 4/5 bottles leak!!
