Wow!! OK; man this is hard to assess If all these "dark spots" (not just on your photos but others' too!) aren't gunk but are really just silver - that is, if they are all "clean" - then... what were we talking about again? Don't mean to be flippant, certainly.The dark spots are actually silver spots, the lighting makes them look dark for some reason. They appear to be scuff marks almost but I strongly doubt that is what caused them. Who know what it was, @thekarmawhore put forth an interesting hypothesis. I am far from an expert in electronics.
Here is a picture without flash, as you can see there is the gold contact and the spots are actually silver. The dark spots within the silver are gold. Hopefully that makes sense, sorry for the low quality pic.

I was able to clean off the crescent shaped gunk with the pointy end of a bamboo skewer that I repeatedly dipped in isopropyl alcohol. Performance seems to be the same, no improvement, but I haven't seemed to notice any decrease in performance since I first got my hopper, still hitting like a champ.

Stainless Steel w/o extra chips
Ah ok, I understand where now, the rim around the PCB. That is a huge gob.Look on the silver part of the grasshopper body itself, on the perimeter near the walls. The ring of metal outside of the battery and pcb. There is a huge crescent shaped brown glob of gunk in the first picture, at roughly 6:00.
Other people have similarly shaped globs of different sizes:
Very Small, About 4:00-
Very Big, About 7:00-
Mine is eight weeks old. That could be why I had the gunk. It didnt seem to affect performance in my case, so I don't think it's a major concern. I just find it odd that they all share the same shape.Ah ok, I understand where now, the rim around the PCB. That is a huge gob.
I have had my hopper for about 3 weeks, use it a dozen times or more a day, but don't get any gunk in that section at all. Is it too soon to tell? I mean, for example is your hopper older?
What camera did you take these with? How did you get that even and diffuse yet not harsh lighting down the tube?
Here's a brand new led flashlight bare driver board that already shows the grid pattern. Add a little wear to the plating and it would look just like the GH pcb.

- Whenever I install a battery in the TI, the lights turn on red briefly as the backend makes contact with the battery. This doesn't happen on the SS.
And now my mouthpiece isn't screwing on completely, but the screen is tightly seated. I'm 99% sure it's because material is lodged in the threads. Time for an ISO soak. Hopefully that will solve the problem...
Any suggestions other than an ISO soak?
Thanks! Regular q-tip okay or do I need a precision q-tip?Iso soak then run a qtip around the threads. Same thing happened to me, and the qtip helped.
Before you finish soaking it, get a pipecleaner, bent-to-shape, and give the threads a good wipe over and rinse it a few times. That should do the job pretty well, I've had success doing similar without soaking it.And now my mouthpiece isn't screwing on completely, but the screen is tightly seated.

If simple iso soak doesn't clear the threads, you might try the tweezer tool to loosen the screen a turn or two, with iso, to free up anything stuck way down in the mouthpiece's threads.And now my mouthpiece isn't screwing on completely, but the screen is tightly seated.

Maybe if your hopper was warm it would make it easier to remove. I find that helps with a lot of my vapes. Either try right after you finish a chamber, or maybe take a few hits from an empty chamber at temp 5.Being ambitious I thought to take the screen out to do a good clean on everything, but my pointy tweezers either aren't point enough (they sure seem razor pointy though!) or that screen is in there hard. So I left it alone. I guess if it isn't easy to get out, I shouldn't risk the tweezers marring the screen holes from the forces needed to be applied to get it to move. Not willing to push that envelope.

I think it's best not to mess with the mouthpiece screen unless you're having issues with it. I clean my mouthpiece by soaking the entire piece in iso and using a toothpick or pipe cleaner for the stubborn parts near the tip.
I got them for my pax1 too! I think I got the tip from Vape Critic. Hope I can find them.Perhaps dental brushes dipped in iso work well? I used to use them when I had to clean my pax.
Had an interesting observation tonite:
I just got a few more batteries from HL. I decided for some reason to check them in the hopper. But before doing so, checked the battery level in my UM20. They were all at least 97%. Fine.
So I screwed them in one at a time, and sonofabitch, one of the batteries (just one) wouldn't kick the hopper into any status. Dead. Take it out, check on the Nitecore, it says 97%. Put it back in, click it, and nothing!
Has this happened to anyone?!?
maybe use a hollow straw as a barrier?I wish I could fit leads from my multimeter down in there without touching the sides and being able to see.
as far as I know... and mentioned in this thread....I think you have to send it to ghl....After a little over a month my blue ti unit stopped heating. The lights turn from red to blue within a second regardless of temp setting. I can hear clicking inside the unit as normal. However, I do not get heat and it shuts down as if It is not detecting my suction.
