reasonably powerful for a cheap module nice and short module, would be easy to build a compact pointer
CONS
trim-pot was too filled with glue to do anything with
I unsoldered the tiny trimpot, and soldered in my own 10k trimpot. Adjusting the trimpot, I was able to push it to nearly 400ma current draw (at the driver board, not the diode) before it died. The ... (read full review)

OK product, current draw at 4.2V cell was about 150mA or so. Diode diode is driven at about 75mA current. (somewhat low driver efficiency) If you want to adjust output you can do it by changing curre... (read full review)
