Review title: good product but voltage makes difference
Product review: So i bought this gun for work on farm machinery and found that it does not preform as well as with the 14 and 18 volt models. puts out less than half the amount of grease than the 18 volt. i greased one hub with the 12 volt in the same time an 18 volt greased 3 on the low setting. 12 volt does not have the high low selection.
