Thank you all! After watching the video I guess filling my own cartos is not as big of a deal as I thought. Truth is, I thought it would be a major pain in the backside so I was trying to avoid it. I also did not know that my bloog battery which I will say seems to be a great battery would work with these other brands of cartos. You guys are awesome! I'm really happy to find out that my money has not been totally wasted since I can use the batteries with other brands. I didn't know they were interchangeable. I'll do some experimenting and see what I come up with. One question....... refilling my own cartos will I run into the liquid dumping out into my mouth? I had a blucig do that and it was disgusting to say the least! Is it a matter of simply doing it right or is there more to know in order to avoid that?
