Disposable CO2 cylinder, easy installation and replacement.
The product to properly packed. I faced a problem in installation,no instruction booklet is present.Manually had to puncture the cylinder,most of the gas gets wasted.I don't know what is creating a problem, cylinder or the regulator?? Still cylinder lasts up to 20 day ,running after running 8 yrs a day. Over all experience is good with indiefur.
