Review (1/5): Waste of money
I bought these to use to dispense mineral spirits and denatured alcohol in my woodworking shop. I figured that if they could be used with acetone nail polish remover, they would certainly hold up for the less volatile solutions above. In both cases, they worked the first time I used them on the first day. But the next day, both of them where frozen so that the pump would not spring back to allow the liquid to be dispensed. I couldn't even get them to pop back out by pulling on the pump pad. Now they are just bottles that I need to open and pour the liquid unto the rag, since the pump is useless. I would not recommend these.
