This machine has made our co-packing experience for thick liquids so much easier. We were using the manual version before and it was doing its job, but the foot pedal is what maximized our packing speed.The only thing I found difficult to understand was how to hook up the air compressor. The manual didn't really explain it, but luckily I had a air compressor kit with all kinds of fittings and figured it out myself. It really wasn't too hard once I had what I needed.Kraigg Napiontek
