I'm curious also and hope some members will weigh in. I recently read a magazine review that made very favorable comments as well as described the inner workings. I wish I had paid more attention and could give details, all I know is its on the magazine racks now. I'm going to go back and see if I can find it again. I like the looks of Paras new LDAs with the light mount. With Streamlight's light/laser combo on, one would perhaps make a nice nighttime bedside companion.
