I just brought a buck naked express today and it worked for about 2 hours then it stopped .. it's fully charged and I can't even hear the fire noise but the button and lighting up .. I'm not sure to Whether or not it's clogged or not but I haven't even had it for 24 hours so I don't think that's the case . I attempted to unclog it but the silver piece won't unscrew for me to get into the tank .. at this point anything will be helpful lol
