Does anyone know what size o-rings the DQG Spy takes? I’m not sure how to measure them. Mine is eating o-rings right now, so would like to get a bunch more.
Thanks a bunch for the run times. Very impressive that it can still push out 60 lumens after 20 minutes on high.
Also awesome pics, love the comparisons with other lights!
I’d like to know also as mine is eating them too. As I stated above, all my DQG lights are O-ring eaters.
Just spotted there is a DQG charger for it now and it looks very cool 
Just received the Spy/Fairy charger. It has a red LED in it and the LED goes out once the 10180 cell is charged. Right after the red LED went out I took a measurement and it charged the cell to 4.15 Volts.
I received three of the PSK mini containers. Two of the PSK-M and one of the smaller PSK-S. Unlike UPz’ review, neither of them came with O-rings. I had some O-rings of the correct size for the PSK’s but like all DQG items in my experience, the containers just chewed them up. 
The tiny PSK-S is pretty much useless, (unless you’re going to use it as a battery spacer), as it’s so small I doubt if it would even hold two aspirin tablets.
A 10180 cell fits into the larger PSK-M nicely but as UPz stated, the cell will rattle a little but a small piece of foam solved that problem.
An interesting fact is the tops of both capsules are interchangeable. I used the top from the small PSK-S on the larger PSK-M capsule and now with a 10180 cell in it, it’s 1/8” shorter and there’s no battery rattle. Also, the small PSK-S with the PSK-M top is now 1/8” larger and a little more useful.
cnqualitygoods web site leaves a lot to be desired. I cannot make a purchase without providing some personal information that isn’t collected over https. I thought I would create an account and that doesn’t seem to be https: either for collecting passwords :-/
I found them at CNQUALITYGOODS. Ten for $1.10 under the category of “Waterproof O-rings”.
I also wired brushed, (brass), all the threads on the Fairy and Spy and then coated the threads and O-rings with fluorinated grease. Now they both work like they should and aren’t eating up the O-rings.
I would just like to say thank you to everyone who commented about this light, and to UPz for the review. This, combined with the titanium necklace I wear it on, is one of my most treasured belongings that I’ve been wearing for about 2 months now.
The chain I have it on is a 24”, 4mm thick titanium wheat chain, from TitaniumKay I bought on Amazon. I have it attached to the necklace with an old surgical steel earring. I absolutely love this light.
I took a few pictures of it’s awesomeness.
Very nice Lotus! I wear mine on a necklace too.
Wanted to add, this Spy/Fairy charger is a “must have” for anyone who has either light. Mine is now charging my 10180 cells to 4.17V. It really is a great product.
Wow, Just absolutely beautiful, Thank You very much for all of this information…!!
There is a sale at the moment and as of this post I believe it last for about 4-5 more days at GearBest, I know not everyone’s favorite but the prices on the Spy, Fairy, AA and much more are all now within my reach.
I had a lot of questions I was curious about since I have quit a few of DQG items in my cart currently, so did a quick Google and of course where do I find all my answers & all in one place…? BLF…Awesome. Thanks Again…
