I have a pump oiler from Pressol and find that thing terrible. If you need it, one must only times the pump for a while, to what's coming, and then comes right a giant swing. And when the bottle is, it inevitably runs out.
For coarse Schlosser and einsauen well, but I want it but can better dosing.
I take this bottle here now for Ballistol.
The tube can be further drawn out or get stuck with the hex nut. The nozzle can turn and so close, very good for transportation !!!
In addition, you can vote on the viscosity of the oil through this nozzle.
Conclusion: highly recommended, primitive but well, I would buy again.
