Jim Barrett sold me a set of aftermarket milk cans with large magnets years ago when he was working for Davis Electronics in Milford, OH. I set my milk platform track at 20 volts and the cans cleanly exit my 3472 and remain upright 99.99% of the time.
If you can find the large magnet replacement cans, they are exponentially better than the small magnet cans.
