I'm pleased with mine for what it is. The Golden Dragon has a nice smooth beam. I'm sure you can measure some efficiency difference between the Golden Dragon and the latest, highest binned crees, but it is a modern efficient LED. It's not like the older 5mm's or Luxeon I's or something. I picked the AA-S1 over one of the Akory 106 variants because of the Golden Dragon. If you don't like it or decide to change it later, the light comes apart easy and could be modded.
Finish quality is good for a bargain light, but a step lower than Fenix or Quark. I'd say it's like a Romisen with very coarse threading. The color not being black hides some of the scratches and chips. I dropped mine a few months ago and broke the driver. A little bit of work with the dremmel and it can fit most of the 17mm drivers from DX. I put a 5-mode in mine and it works great.
