I just got my 808 and 901 in the mail today. I tied the 808 first and found it tough to suck air through. I eventually got it to produce a good vapor but it still seems too hard to take a drag from. I moved on to the 901 and that seemed better. I was only taking a drag here and there. It was definitely better than the 808 but I am still not satisfied. Is there something I can do differently to make the air flow a little better? I am sure there are already posts about this and hopefully someone can point me in the right direction. Thanks in advance for the help.
