I'm not able to reply in the big thread about Blu Plus because this is my first post so I thought I'd share here. I figured out a way to refill the Blu Plus tanks. It's pretty straightforward. I try to hit every gory detail below so it may sound complicated but... it's just a little wordy.
I start by taking a sharp knife and making a slit down the side of the tank through the black covering. You can then peel off the black "tape", revealing the metal tank. Then take a nail or a tap and tap a small dent about in the middle of the SIDE of the tank. Securing the tank to the edge of a 2x4 or other board with tape (tightly) helps with the tapping and drilling (next). After that I use a 1/8" drill bit in my Dremel and run it at medium speed (still pretty fast for a drill bit) and slowly drill a 1/8" hole in the side of the tank: the dent you make will hold the bit in place as you drill. If you go slow with the hole pointing horizontally (not up), you can drill the 1/8" hole without hitting the inner metal "straw" that is inside the tank. You now have a "naked" tank with a 1/8" hole in the middle of the side.
Once the hole is drilled, I take it inside and wash the tank out with hot water in a filling syringe, squirting the hot water down into the hole and out: washing out any metal particles that might have gotten in (never found any in the 2 tanks I've done, but just to be sure). After that, I blow air through the hole with my spray air duster (straw attached) with the hole facing down and even through the back draw hole to be sure it's relatively dry.
Refill through the hole (tank laying horizontal: hole facing up) with my e-juice until e-juice starts to run out and then wipe off the excess. Then I cut a section of 3/8" heat shrink tubing that is about 1/16" longer than the tank and let the excess stick over the back side (where you draw). Once you shrink that with your lighter or torch, the heat shrink tubing seals the hole and curls over the mouthpiece perfectly. Looks nice. And it works. It sounds complicated but it's really not. Takes about 10 minutes to refill the first time and then after that, only a few minutes to peel off the heat shrink tubing (easy), refill, and put on another piece of tubing and shrink it. How many times can you refill it, I don't know, but I suspect as many times as you can something like a mini protank before you need to replace the coil or wick (read on).
Now, I do have two issues that I'm hoping to get feedback on here. First, I seem to only get about 200 puffs after a VG juice refill before it starts tasting burnt. Tastes kinda like when the rubber gasket in an atomizer burns a bit. I think the VG juice might be too thick for this setup? Maybe I should try 50/50? Hoping someone else will try this method and we can refine it.
The only other negative is that the heat shrink tubing, while it makes the tank look brand new, is a little thicker than the original covering, so the refilled tank won't fit back into your Blu case. Not a big deal for me.
Now, a note or two on what I found actually tearing apart these Blu Plus tanks. I completely disassembled (by basically tearing it apart with vice grips) one tank to see what I was dealing with. I have several hundred dollars worth of protanks, protank 2, mini protanks, Egos, iTaste, etc. and I was rewrapping my coils on a regular basis before I tried Blu Plus. I can tell you after ripping these tanks apart that they ARE in fact REAL tanks! They appear to be constructed exactly like a mini protank... just much smaller: probably why I get as much vapor out of these as I do my expensive setups. There is no gauze or filler whatsoever. On the threaded side, it has basically an identical setup to a protank: what appears to be silica wick with a coil wrapped around it. The wick is fed in a similar manner as a protank: the two ends of the wick stick out into the sides where the juice is and soaks up juice from the tank. The only thing I saw by my deconstruction that I didn't "like" was that the part where the coil wires go to the threaded aperture appears to be a rubber gasket (like a protank coil) on one side but the other side looks (under high magnification) like it might be some sort of epoxy. I guess as long as it doesn't get "burnt" and go into your lungs, that's OK.
Hoping to get some dialog going so we can refine this refilling process.
