Careful what you dispense
Bought a couple of these to dispense various chemicals in the workshop:  alcohol, acetone, and mineral spirits.  The suction mechanism did NOT like the acetone and quickly stopped sucking.<br /><br />Interestingly, after flushing with water, it did start functioning again, so not all was lost.  But if you intend to put something not-so-benign in them, consider yourself forewarned.<br /><br />Other wise they work fine, and as advertised.
