a quick hack fixes the over dispensing problem [SEP] i thought i was so great yes i had read all the reviews saying these tubes dispense far too much sanitizer at once but i was going to be careful not like those other amazon customers who do not know how to work a squeeze bottle well the bottles arrived and sure enough they are so determined to be leak proof that when you squeeze them nothing happens until all of a sudden an olive sized dollop of product comes out in one big blurp being gentle does not help the dispensing is all or nothing i might try to macgyver a solution by poking a small hole somewhere to try to fix this problem but for now these bottles are too annoying to use the good fixed the all or nothing dispensing problem by using scissors to make a tiny slit in one of the petals surrounding the tiny opening now a slight squeeze gives the desired small amount of product
