I bought this little machine out of curiosity, has a very low price.
It's good LeMaitre is sturdy and reliable.
It is a machine designed to benefit the world of visual effects style plates, film, or professionals of all kinds who need a portable machine.
The cartridge system allows pressurized fluid to bypass pump, lost in noise, a good point.
The other advantage is that the machine can operate for ten minutes without being connected to the mains, it can be a real advantage for a lot of uses.
Otherwise the rest, but it is well built, a release button on the top of the box and knob flow control.
Level flow precisely sends its not bad for a small machine like that.
