So my Q8 seems great. No scratches, not dirt, led's fairly well aligned (not quite dead perfect, but ok). The screws are nice quality with the possible exception of the LED board center screw that still doesn't look bad. The indicator LED's are not quite even (mabe 2x different), but they work, and it's not an issue to me. My battery tube initially located just short of perfect alignment, and after a little use it's already gone past perfect alignment, so that just proves it's not a reasonable thing to expect and isn't possible to deliver, at least not without a completely redesigned closure mechanism. It definitely has the bump-on bump off feature. Handy for slamming it down on the table to turn it off. Not dependable for biking, but it's not uncommon from what I can tell.
Otherwise, it works great. I do have bistro-HD running on it (not the posted version, it doesn't work). The light does seem to have switch bouncing (mostly simple fix), so I'm guessing my bench setups don't because of either the big OTSM cap they have (even when I'm not testing them for OTSM) and/or maybe the lack of R1/R2 impacts C1 stability, not sure, but it bounces, and the bouncing finds every little race in the code real fast. There's still some rare lockup so maybe it find that soon or maybe I won't.
Nice light, well done.

EDIT: that was Nil, at Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light - #13392 by Nil
recommended this one. I agree it looks better than the other choices.
Removing the switch cover
You can scratch the black ring, try to wrap one layer of tape arround the needle noses of the pliers
Just preformed the requested test. Deactivation of the switch LED has no affect on the constant glowing of the main LED’s.
I will now disassemble for inspection of the SMD components on the driver. I’ll be sure to get some close up photos for documentation and analysis.
Received my Q8 (second batch).
Construction cannot be faulted, though I haven’t turned on yet (BT VTC6s still charging).
Tripod hole is perfect!
Thanks!
Everything I have seen suggested so far seems pretty generic. The ones that already come with some flashlights seem more durable and of course purpose made. Was hoping there was a place to buy these.
Like this one from the Lumintop PS03 reviewed here.
So many nice lights have tripod mounts now. Hopefully someone will produce a quality lanyard screw for the aftermarket. Guess I could try contacting Lumintop.
Okay, this is a puzzling thing to say. Bicycles have vertical loads (bumps on ground). Assuming the flashlight is not pointed straight up at the sky, why would the batteries ever loose contact?
Tks all, I guess it could be this cover then, if it can move even further over from what I saw…I was imagining a flat switch underneath but I guess not. So it looks like there is a mobile peg type switch underneath? I don’t currently have access, but should this weekend and will try replacing the cover.
TY for the suggestion, I wouldn’t want to scratch a gift.
Got it opened up and snapped a few photos. I’m not seeing anything that I think may be causing the issue. I’ve inspected all the closely spaced pins on the different components and I don’t see any obvious solder bridges. I’ll go ahead and give it a spray down with contact cleaner to see if that helps any. Beyond cleaning, what else should I do? Is there any testing that I should do with my DMM?
This was posted earlier here. Maybe it will give you a better understanding.
With enough experience I might learn to depend on it, but there are times where I wouldn't want to find out by experimenting. I'm not sure either way if it will be good enough, but this everything bumps only up and down argument sounds a bit oversimplified for representing reality too me. You may bicycle differently from me. Cruising around in the park is one thing. This is a commonly reported issue for cycling too. I wouldn't call it a flaw exactly, just not a strength.
Well, don’t take this too seriously (I don’t), but after pocket carrying it for 2 days, I’ve decided that the Q8 will not be my new EDC light.
My normal attire is cargo shorts and a polo shirt, and the left cargo pocket is usually dedicated to a tube light, either 18650 or 18350. If there’s a Q8 there, I don’t really enjoy biking (the Q8 has to go in the pannier), and the weight is quite noticeable. Shocking, right?
I’ll try just about anything in my EDC rotation, but after 2 days carrying the Q8, I’m looking forward to the return of my jaxman e2/convoy s2+ hybrid nichia 18350. Just in (the unlikely) case anybody else was wondering. 
When my grenade pouch comes in, I might try it again.
You shouldn’t be carrying the Q8 around in a pocket, any fool can see that with the correct D ring installed it is meant to be a keyring light.
/\ … Yep…… 
ElginAgain double check for micro traces of solder between the pins of U2, on the side with U2 printed, it probably is just flux but you never know 
Cheers David
I can’t imagine the Q8 as a EDC light unless it was in a pack. Yup, I’d choose another. Great light just not a pocket light. But maybe on the bill of a baseball cap? (just kidding!)
Ah, good. Having the hardware should make it a lot easier to develop. I gave it a try briefly and ran into several bugs right away, so I figured I’d wait until it was a little more stable.
Is that easier than long-press-off?
Anyway, I’m still waiting for my Q8 to show up. Looking forward to another toy, particularly since it has extra features none of my other lights have. (no idea when it’ll be here, but hopefully soon)
I use the Q8 as a riding light and have had not lost contact once with my mount. I only ride on rough trails at worst and have no issues hitting cracked spots, riding over branches, or going up/down curbs. It is true that most forces of hitting something stiff, or a hard drop will not cause the light to shut off because the forces are mostly perpendicular to the batteries. It isn’t very hard to understand. It would take something like rough mountain biking and a small tree causing the wheel to jolt in an uncontrolled manner to cause disconnect. Due to the weight of the light my mount would be insufficient to handle the sudden repeated forces of such riding. I don’t think the disconnect “issue” is real because riding that would cause it would break the mount trying to hold over half a kilogram of flashlight in place. If you are doing that kind of riding and take safety seriously you should be using a light on your helmet so you can quickly survey the uneven terrain. A handlebar mounted light would be ill-advised for that kind of terrain because the handlebars won’t always be pointed straight.
