how to fix/mod a Prosmoke cart?

[gearjunky]

so I have a Prosmoke ecig that i bought long ago that works terrible so I don't use it much....rather than let it go to waste I vape it occasionally, but the juice never wicks up to the atomizer good enough to vape more than 5 to 10 puffs then it quits giving vape...then I always have to top off the internal cart with more juice and start over. is there any way to mod this Prosmoke cart so it will wick the juice consistently? it's been doing this for the entire year ive owned it...luckily I have several other vape kits that are my main vapes...ive tried everything imaginable to get this thing to vape consistently to no avail. ive heard and read that other vapors have the same problems with the Prosmoke brand ecigs, and I've also read where some folks think their Prosmoke is the best ecig out there...what's up with my Prosmoke?
