Just received my Peak Pacific today. At first I thought I had a problem with the 1xAAA tube, turns out the bottom screw under the tailcap wasn't tight. No problems now. I got the 1xAA tube, 2xAAA tube and the standard 1xAAA tube. Fit and finish are very nice, cosmetically near perfect. Twist on seems a little tough but should improve with time. Brightness is good for a light this size. Appears very nice and white to me anyway. Also, as advertised, the Peak staff were very helpful and quite frankly Top Notch!!! Thanks Peak for a great light and great service!!! I highly recommend this light although I have had it for only a few hours. Doug:)
