True that Tom E. They do seem to shot themselves in the foot with their poor product descriptions. I only buy emitters (good ones) from a few vendors that I know I can trust. I make an exception of those Nichia 219B's because the price is just so crazy low (5 for like $13.xx).
Hopback,
You should get a good light if the Aliexpress company I bought from is indeed KD. Mine seems to be the same quality as the ones I've seen in the various threads. Specifically compared to the light in the OP of this thread, it seems identical except my emitter is on a 20mm base and I mine has the battery tube lables, "Courui", "CREE", and "XM-L2". It seems everyone's is the same so far though. The Courui is probably still new enough and low enough priced that hasn't been copied yet. It sure seems like a lot of light for the price. Nice big, high quality reflector, decent matching, fit and finish. Anodized threads everywhere except pill to head and battery tube to head. Clean, no grease or dirt from the factory in the light. All my lights of similar size and quality cost much more. I'm very happy with mine. Only wish they were 3S with a buck driver stock.
EDIT: Fixed some typos. Seems some of my keys don't respond well anymore. Also added bold wording.
