Bummer. I seen in another thread that if you write the tracking number on a piece of paper, sign your name and leave it that they'll leave the package. That may not be policy though and may not work everywhere. Might be worth a try though.

this is what i do and get it left everytime

Anyone having a problem with the coil somehow shorting out when you put the pins in? On one of mine, the holes are a bit big for the pins, but with both of them, the last time i tried to set them up, they both would short out when i put the pin in. i could take it out and push it down with a needle and the coil would light up, but as soon as i put the pin in, I get the E1 error on the Provari. Ideas?

Make sure the coil isn't touching the deck, but other that that the only thing I can think of is your coil being borderline too low ohms. With the higher ohm loose connection, the prov fires but with the solid connection drops down to it's cutoff point??

Also, If you have a meter, check across the terminal of the 804 to make sure you read an open.

Yeah, I tried the other pins, but those were the same size as the other ones. I even tried switching them between the two Dream's that I have. I managed to get the one working where the pins weren't too small for the holes, but the other one won't work. The coil isn't touching the deck. The only thing I could figure it that there's a problem somewhere in the small hole. I don't have a multimeter at the moment, but once I get one, I'll check that. The one that I did manage to get working seems to be doing fine. The flavor is generally really good and it hits well, but it does seem to have some trouble pulling juice into the chamber. I've tried small and large wicks, and moved them to different spots, but nothing seems to help that part of it. I just put my finger over the hole and pull really hard every few hits and that keeps the juice flowing. I've ordered one of the Kayfun's, though it will probably be another couple of weeks before that arrives. It better be awesome considering the price. :) Anyway, I'll let you know if I figure out what the deal is with the short on the other Dream. It'd be nice to have both running since the draw on the one working is tighter, and I wanted to see how the juice pulled into the chamber on the looser draw one. Oh well.

Yeal, China quality control strikes again. I have four of these now and they're all working well at the moment but two of the four have quality issues.

The biggest issue is one of them doesn't have the groove for the o ring in the top piece. That means that the o ring is pushed out to the end and wasn't sealing when I first got it. I sanded down the tank a little on each end which shortened it slightly and allowed the chimney top to push on into the o ring and seal.

Another one has the slightly larger hole on one side. I'm just putting an extra piece of wire in to tighten the connection.

Keep experimenting with your wick. Hopefully you'll be able to get it wicking great. My only remaining niggle with these is having to plug the mouth piece and fill from the bottom to have 'that didn't spill a drop' refills. To me they're worth it for their smooth operation and great flavor.

Not too long, imho. They seem made for each other.

I have too many to use just one so I couldn't say. Definitely worth the extra length though. The original just holds way too little. The flip side is you fill it so often it becomes secnd nature. I wobder if they could make a wider version with the same innards. Fatter may be better than taller.!

^^^^I really don't understand that but it just goes to show different strokes for different folks I guess. I just don't think he's got a good build going yet. I'm running a 2.1 ohm coil at 4 volts for 7.6 watts and I'm getting more vapor than he was. (~50/50 pg/vg).

As far as flavor, that may be tied to his poor wicking. I've vaped several different devices from 510 attys to cartomizers to ss mesh in a chid, and the 804 tops most of them for me. I once set up my chid with a spin-E coil and that tastes very close to the same as the 804, to my buds at least.

If you push the transport out to about 2:55, start this video, and watch a few seconds, you'll get more of an idea of what the 804 is capable of. Beautiful Dream Rebuildable Atomizer - YouTube

columbus,oh
I have to agree. his build in that second video is too complicated lol. my wickes just circle the coil platform stopping at each juice hole, ive rebuilt the 2 i have many times and never had a problem. It wicks great, always keeps up with my chain vaping even with my .8 ohm coils.
and to be honest the dream bt804 has ruined me to anything else. i cannot get as good a vape from anything not even my drippers. i just wish one of us who knows how this works could build one and send it to pbsusardo so he can see what we mean lol

Well, seeing as DV had them marked down, and seeing as trying a meshed-T3 was a flavorful success: I dropped a dime and ordered one of these.

I'm looking forward to exploring more of this bottom-coil stuff without blowing a whole paycheck on a Terminator, (and yeah - a true Kayfun is ridiculously out of my price-range).

From the various pics and videos, I swear that base/basin endcap is more than 2x taller than it need-be, and man.. I wish someone sold a 'fatty' Vivi Tank.. I've been wishing for squat and fat tanks for a year. Maybe someone will end up rigging a "blown" or lightbulb-style tank.. Or rigging something using the aluminum tank-tubes.. It's not brain-surgery, but sheesh.. THey don't listen.

Thanks for the posts, folks.

Yeal, I think it has some wasted space on both ends. And on the extended version, it would hold a little more if they made a separate chimney for it instead of the little extension that takes up more room in the tank. But, like you say, they don't listen to us lol.

When you get yours, make sure it has a groove in the top piece for the o ring as I have one that doesn't.

Keep us posted on how it goes. :vapor:

I think I'm going to tear it down, clean it, and toss it into the "... do I do with these" parts-bin..

It leaks; it's a pain to fill; the pins simply don't lock into the holes until I hit 30awg.

I love the flavor, but it's really a bad design - the chimney is vastly too thick for the tank-space in which it sits. And, that o-ring in the top is locked ok, but trying to refill/fill will unscrew the chimney, more often than not.

If I had a tap & die set, I think I'd drill & tap a set-screw in the base of the chimney, against the threads. (But it still needs a potbelly tank to at least run 2.5ml). Drilling and tapping the top-cap for a fill hole is another alternative.

Be sure and tighten the chimney down as it's not needed for juice control. The best way to fill these imo is to plug the mouth piece and fill from the bottom. I use the plunger from a 1mm syringe that I've trimmed down.

I just put another short piece of wire in the one I have that has a larger pin hole.

Sorry you're not happy with yours. I think I'm going to quit recommending them as there's no way to tell if the owner will enjoy them enough to put up with their quirks.

I use a Qtip when I fill upside down. As an added bonus it does a little cleaning when you remove it. I think the key here is to get a lot of wick exposed to the juice. That's why I like the XC-116. It's a fat wick and just gets bent down when you put the chimney on. juice has free flow and the wick absorbs it all. And the fat wick inhibits air flow a bit. It all works together like it was designed from scratch by a. einstein.
I have a Terminator C now that I will build. I expect it to be similiar and there is a guy in Poland bulding Kayfun innards for it. That there is kayfake nirvana. A fat tank to go with your fat wick!
