Chill your beer, hook up to CO2 and SHAKE THE CRAP OUTTA IT! I use mine mostly for carbonated water, juice, or whatever I feel like experimenting with. You have to set the PSI to where you want it, and shake it to dissolve the CO2 until it equalizes (keep shaking till your tank stops pushing CO2). When you disconnect it make sure the poppet isn't leaking; I have this issue and have read others do as well, it will slowly leak unless it's seated just right. Just wiggle it around to seal it if it leaks some. Hope this helps!
