    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:- Cheap - Driver can be adjusted - Easy to install on "pen" type pointers available on DX - Initially did draw 300mA, adjusting to 600 mA did not change the visual effect.

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Good build quality, strong clear beam. Instead of try adjusting the focusing lens, turning the whole outer brass assembly a couple of rounds counterclockwise, a burning focus may be established about 10 cm from the laser. The original focus was adjusted perfec... Read more
