So you didn't think I was going to tell you lot about a product trial with out getting in on it myself.
Well it arrived on the Dec. 21st.
Nice packaging and overall nice feel and finish to the unit. Same as all the others as far as what's in the box.
The first thing I did was take the back off. Then I emailed them and said the same thing. I was not happy about the air being drawn into the chamber coming from inside the electronics and battery compartment. 18500 li-ion for those who made speculations early on. Solder connections so would involve a little bit of know how to replace.
I decided to try it as is. As anyone who bought from a vendor would. The button sticks on unless you hit it in the right place. As you can see above left, the little white switch on the PCB is not central to the metal switch, which is causing me problems. Not a big problem but it does stick on.
So burn off's. Using a fully charged battery. 3 hours so it's a 500mah charger on the board where the port is. Top left hand corner.
A bit of manufacturing process oil smoked off the screen. Hotspots on the screen. The thing was glowing red. Having used a MFLB I knew this wasn't going to be good. So I took the screen out, very easy, and gave it a bend here and a bend there and put it back in. Same thing with the smoke on burn off, this time it's the oils in my skin that caused it, if you held the button down for 5 seconds ish it's up to red heat again.
I had a quick go indoors where I usually vape and it's now confined to only being used in the privacy of my shed.
Myself and
@Ruta set about trying it out again with the original screen and then another of the two spares you get. Still the same thing. It smokes. It smokes because the line between vaporizing and burning, charring, carbonizing, what ever you want to call it, was too fine. Without a load in it the screen was still getting a faint red glow. If you look into the bowl with the lights low you could see it. As the air was getting in every where there was no way to cool it down using draw technique.
It's confined to the outdoors because I forgotten how strong the smell of burnt weed actually was.
Not being one to give in I'm going to persevere and have been in contact with Atman since day one. I will not be doing much more with the Hachi until after the New Year as I have family here.
I have had a bit more of a bugger around and am now happy I know where the air I draw in is coming from.
This has been achieved with hot melt glue and everyone's favorite shimming material. The humble rolling paper.
The lid has been cut in two. Rolling papers have been folded over a few times to give a reasonable thickness to them. The half lid is then pressed in, the screws replaced and paper trimmed.
Hot melt glue has been used to seal the hole where the heater wires come thru. I do not mind this type of glue here as it won't get hot enough for me to worry about. It should never reach the temperature to become molten and off gas as it's on the outside of the heat chamber. Hot glue and rolling papers are all I had to hand a silicone seal would be better.
I will stick with it and once I have some time I am going to continue to see if I can get better results.
The air now is only coming in under the lid so it's a lot more throttled. I used rolling papers to seal the lid and drew in thru the mouthpiece, 510 drip tip, there is nothing of any significance coming from anywhere else. You only need lift the lid a tiny bit to feel the difference. The screen fitted at the mo is not getting as hot so it will get changed and some more tinkering will be in order. At least now I have the ability to cool the screen with draw technique which I never had.
I have been able to get some tasty hits but nothing satisfying of yet.
@poonman I had a little chuckle to myself when you mentioned Yocan. Their 94f was my first venture in the vape world. It was attached to an under powered Vamo with a pair of 18650's in series. I could get it to work but it took some modifying and was hot as hell to use.
