Review on Efficient and Versatile: Jebao DP-3 Programmable Auto Dosing Pump with 3 Channels in Sleek Black by Jill Berg

That's a lot. Easy to set up and calibrate but I noticed that when calibrating to 100ml it dispensed 2ml instead of 1ml so I calibrated to 50ml and now it dispenses correctly. 1 star for that. My instructions came in English, I saw some reviews here that said they were in Chinese. In general, the purchase is satisfied. Update April 2, 2019: My lines kept emptying with this pump, which was annoying. This can be remedied by installing non-return valves at the start of the outlet lines. Seems to be working fine now. Deducting a star as this is really a fundamental element of what this pump is supposed to do and I don't need to add any extra detail. Even if I don't regret it
