I've tried a few of those hash presses........I sugest keping your hash in a powder........Put it in a small glass jar...
This keps it easyer to smoke , and dry so it does'nt mold. If hash isnt so gummy it self presses then why bother........If you are having truble making bubly hash check out Bubblebag.com
Peacemaker* yes i have tried, it was actually one of the best i had smoked early on, but honestly I have never seen it since. Its gotta be about 5 years now.
