I've got a couple of reviews of Nuwai lights on my Reviews page here:

Note, the reviews nearer the bottom of the page are the best, earlier ones were done before I had a set format, and really need to be re-written...alas, no time to do it!
In general with Nuwai lights: Excellent value for money, bright, durable. Beam quality can be a little less than brilliant, but never to the point of impacting the usability of the light. ALX-113AA has recently earned itself the title of "most often grabbed light in the house" for a variety of tasks. It's the most recent addition to my reviews page if I remember correctly.
