Got the Sunwayman D40A today, I am very impressed with it.
I put 4 AA batteries in it and tested it. It has a bunch of modes that can be pretty useful under the right circumstances- 4 regular output modes +moonlight mode
Strobe, as well as police like strobe sequence. It has SOS strobe, and a beacon mode. This one will be real fun to go out at night with the kids and throw in the neighborhood.
Got a Sunwayman V11R on the way as well, that will be an EDC flashlight.
