They work great if you use them within a few weeks of receiving them and keep using them. I have found that if you leave them on for too long the rollers will permanently squeeze the silicone hose and the only way to open it again is to push something through the hose with considerable force or just swap out the silicone hose. In terms of accuracy, reproducibility, and reliability, I've found them all to dispense around 1mL per second while running at 12V, within the range of around 0.2mL…

Received this on time and in well protected packaging. I connected the pump to the power supply and cranked it up to 12V. The motor turned on, but the inner rollers didn't move until I messed with it a bit. The white case that the tube is in is quite flexible so I'm not sure how well the inside of the tube seals. I took one end of the tube and dipped it in water to test, but nothing happened. Nothing sucked. After playing around with it a bit I thought it was a waste of $10 and figured I'd kill
