im not knocking one over the other ,i mean i called volcano to ask if they had the blue ,i left a message ,and like 20min later she called back ,but they werent carrying it anymore (in blue) ,cignot had it so i ordered it today . cant wait . price wise they seem very close the inferno was a little higher ,but there kit came with a 1000 bat ,and a 600 pass through with there kit . cignot came with 2 600 batts ,(1000 was a 4 dollar up charge per batt) . i also ordered the pass through 600 from them ,and the car charger ,because it says you can use the pass thru in your car . i mean pass thru and charge in front of my pc ,and car . with 2 600 batts i should be good . i also bought some pg and vg juice from them whats the difference ,and why do you need to mix them like 60/40 and stuff ive heard people saying?
