I have had one for about a year now .I have run over 200 lbs of grain through it without any problems, that is unless you use the handle that they charge an extra $5.00 for. As there add says almost useless. Just use a power drill motor but try to keep speed around 200--400 RPM
Has anyone tried the DC pumps from . They operate on 12 volts D.C.
