Thanks MoobyGhost.
I'm still a newbie, about 8 days smoke free. I know most people here don't like the Blu, but thought it would be worth mentioning that this works very well on the Blu.
I found myself going through 4 of the Blu Carts per day, so my supply quickly ran out.
Fortunately the ECF Prize Patrol gave me a $25 Gift Cert. at LiteCigUSA.Net, and I got my free juice on saturday. I spent the last 3 days trying to find a good way to refil the carts. I tried the Blue Foam and Fluval. I also tryed the B.F.D. Which worked OK, but got alot of leakage. The Blue Foam Leaked pretty bad, and the Fluval was the opposite, it didn't leak, but also didn't wick very well. And I got really bad burned plastic taste with both. Either it's not wicking well enough, or the material itself adds the taste.
I just tried the PTB today and It is by far the BEST filler material for the Blu.
Wicks VERY well, with very little leakage. It only leaks If I store the Cig Batty Side Down. Laying it flat is best, it doesn't leak, but the liquid flows and gets the keeps the Atty wet. But even storing Atty Side Down, it still wicks well. The primer puff might be a little dry, but after that it's great.
I've also noticed a greater saturation of flavor in the Vapor. I think I read here or saw on YT that is due to the material being Nylon, instead of plastic.
And I've done 2 carts so far, and they have been sucked pretty dry. Only probably about 1 drop clinging to the sides of the cart.
And I only get the burned plastic taste when it's completely dry.
Thanks again, this is by far the best filler for the Blu.
