Don't waste your money. 1 star is being generous.
I would give this product zero stars if possible.  Not only does it seem to be poorly 3d printed, but its overall junk. The plungers weren't even finished properly.<br /><br />Top that off with having to pay to return an unfinished product is the icing on the cake.<br /><br />Update:  getting my refund was a nightmare too.  That was mostly Amazon's fault.
