Works pretty well, I only have a couple of minor critiques. I wish the hose was a little bit longer, just a foot or so, and the pump mechanism isn't as good with low viscosity fluids as I would like. You have to do too much pumping to get the fluid out due to internal leakage in the pump. If you're getting this for gear oil or something similar, it should be fine. I got this for automatic transmission fluid and it struggles a little bit.
