Pros:
Beautiful copper design, if you want it (and if you don't now, you will)
High CRI, Nichia 219b emitter
Brilliant, well-machined quick-release with a canted coil spring
Easy, one-handed twisty - great threads, lubrication, and spring tension
Nifty glow-in-the-dark material around the emitter beats GITD o-rings (e.g. Worm SS)
Good levels for most uses
Great feel, heft in the hand
Cons:
Body made in China with occasional, small quality issues
Personal preference - start level is Low; I prefer Medium for a key-chain light
I've tried a whole bunch of AAA lights including Olight i3s, Astrolux A01, Thrunite Titanium TI3 Neutral White, Fenix LD02, and Lumintop Stainless Steel Worm. I always found myself lusting after the copper beauty that Prometheus had created, and indeed, they all fall short. The Olight i3s is a great buy, but a little cold on color and chintzy on the chain; Astrolux is cheap and had a way-off-center emitter (though they have a Nichia+copper option, I didn't like the design enough); Thrunite TI3 NW is bright, solid, and I like the XP-L V4 emitter pattern, but the color, if warm, was heavily green-tinted (vs the rosier Nichia); the Fenix LD02 is a very cold-blue-colored light with a style I didn't like for a key-chain, including the rear clicky and 'tactical' look.
The closest competition is, of course, the Lumintop Worm - I believe that Lumintop is the China-based manufacturer for the Prometheus Beta as well. While I don't have the Nichia+copper version, the battery spring on my 2015 Stainless Steel Worm is too tight to generally operate with one hand. It additionally lacks the quick-release that puts the icing on this Prometheus Beta.
As for the bad, my Copper Beta QRv2 has a *slightly* off-center emitter. But seriously, beyond the mental factor for an $80 light, it's completely unnoticeable in the beam pattern. As far as levels, I have a preferential beef. I actually prefer the M/L/H ordering and 5-lumen Low on the Worm vs the L/M/H Beta and its 1-lumen Low. Point - 90% of the time, you turn on a key-chain light needing Medium or High. A firefly-ish, 1-lumen Low is great for saving battery life and night vision in certain circumstances, but it's rarely the level I actually want. I don't take a heavy copper light backpacking. That said, if you are going to have a 1 lumen or less Low, it should be first, so Prometheus got that right, IMHO.
A note about that 'copper metal smell' which annoys some - it's not the smell of metal, but the smell of copper ions killing bacteria. Copper is naturally bactericidal and humans are good at smelling death. So, change your mind and embrace the sanitary gleam of copper ;-)
All said, I'd buy the Beta QRv2 again for its beautiful mix of design and function. Perfection doesn't exist, but this is as close as anything. Plus, the guy who runs Prometheus is a fantastic U.S. designer and machinist, worthy of some hard-earned dough for a fantastic piece of work.

I ALMOST knocked off a star for ease of use. The light comes with no instructions and is not intuitive as to how to cycle through the power levels. I did immediately intuit this is a twist on/off mechanism but it did not occur to me that you could twist it on/off multiple times to cycle through the power levels. When I first activated the light it was on LOW and my first reaction was...meh, I have had better $1 lights...but once I came back here and read reviews about how to use it I cycled up to full power upon the third twist on/off and WOW talk about powerful. I am just glad for the on-line reviews where this can be figured out! I strongly suggest a small one sided piece of paper to make this clear to folks since you are risking negative reviews by people who are not willing to research.
