Hi all,
I finally received my package from cnqualitygoods containing the CQG S1 (cool white) and the DQG Mini AAA '1999' stainless steel (neutral white). Shipping was via Sing(apore)Post registered mail which took 20+ days- seems like the package took a boat ride across the Pacific. I had to go to the post office to sign for the delivery as it was registered mail.
My goal for these lights is to find a smaller replacement to a Quark Tactical AA which is carried next to a thin wallet in the front pocket. I opted to try the S1 first due to the smaller diameter and the lack of knurling since the Quark has chewed up the wallet a bit. The Mini AAA's knurling looks and feels similar to the Quark's and I'd expect it to perform about the same.
Some initial impressions:
The S1 is sleek- it's very minimalistic and looks like a small stainless steel rod. It's also fairly slippery and I've dropped it and dented/scratched it slightly already. The edges on the tail are a little bit sharp due to the design while the Mini AAA has softer/rounder edges. Both of the stainless steel lights feel as heavy as the aluminum Quark.
Both have metal tailcaps/button which extend ever so slightly beyond the end of the light which gives a slight wobble when tail standing. However, it makes the switch easier to press since the diameter of the lights are only slightly wider than a AAA. There doesn't appear to be an O-ring between the metal button and the body which allows the button to wiggle a bit from side to side. The Mini AAA's button has more of a travel before the switch is engaged (likely due to being a reverse clicky) and has less resistance than either the S1 or QTA.
Both lights came with dry threads which I suspect is because of the electrical path. Using conductive lubrication will probably be necessary (I only have non-conductive lube, will see if it still works).
The Mini AAA's neutral white LED is slightly pink which gives it an overall brownish tint. In comparison, the Quark's NW XML looks yellowish and the CW CQG S1 looks blue (as expected). I can compare them to a Nichia 219b if there is interest.
The S1 has a forward clicky which makes it easier choosing between High-Medium-Strobe. The Mini AAA has a reverse clicky, which I don't like as much, cycling through High-Medium-Low. My baseline for comparison is the QTA's interface with low and turbo. I very much like the decoupling of the mode selection (based on the head being tight/loose) and the activation (forward clicky for momentary on). UIs are subjective and each has its benefits.
Overall, I am satisfied with the lights. The S1 is a nice thin light which will likely replace the QTA for pocket duty, especially in dressier situations. The Mini AAA will soon get a chance in this role, but the reverse clicky will take a little bit getting used to.
I am not qualified to comment on keychain carry since I keep my keys as light (no pun intended) as possible. The stainless steel definitely adds weight but would survive longer against keys. If the CQG S1 is small enough for keychain carry (see first page for pictures), then the DQG Mini AAA will be just as suitable with a slightly larger diameter but a shorter length.
