This is the perfect first step moving from hand filling to automation. The peristaltic pump is great—I was unaware that pumps like this existed and were affordable too. This pump can run without liquid flowing through it, meaning that you can completely clear out one liquid before changing to another liquid. The process is fast and clean.I run a mostly glycerine based liquid through this machine, which it handles just fine with no lagging.This filler requires constant human supervision thus far, it has not been easy to set to reliably fill my bottles to a specified level. Rather than set the machine to fill a specified volume (100mL for example), the user sets the machine to fill for a certain amount of time, then can fine tune the speed of filling so that the perfect amount is filled. I suppose it must be done this way, but it works and I’m sure I’ll become more adept with the settings in time.All in all this is a great machine and it saves me a massive amount of time, frustration and aching muscles from hand filling with a syringe.I will say that when I first received this machine, it was defective-the pump would not cut on, I expect it was a wiring problem. The return was very simple, didn’t cost me a thing, and they shipped the replacement immediately- they didn’t wait until they received my return to send the replacement. The new one works perfectly.As I always wish when purchasing products from a non-English speaking country, it would be nice if they would have someone who speaks English as their first language to write their instructions. But I figured it out and wrote my own manual for my employees. All good. Overall I am very pleased with this little machine. It makes my life better.
