Brief conclusions:
Dosun R1 builds very solid and has nice quality, output is similar to streamlight luxeon 4AA, runtime is excellent, especially when using NiMH batteries.
For flashaholics in CPF, this light may not bright and small enough, however, if you are looking for a solid 2AA flashlight light that is reliable, bright, easy to operate the multiple functions, it is.
