I purchased 2 15000 bushel bins from these clowns four years ago and have been pleading with them to get the bin sweeps working, I have phoned countless times requesting that they get my sweeps to work, I have tried every thing, they will not work.Today called in again to ask if there is a chance they might get the parts sent out to get them working and got yelled at like its my fault there sweeps have never worked. I'll never buy another thing from these guys. Promised the world get nothing done......JOKE. You know who you are.
