Noticed mention of the core. I recently received a free core from WL in exchange for helping with the website.
While I cannot give power measurements, I can say that other users have reported rock steady output at ~4mW. The transverse mode is a steady TEM00.
It is also IR filtered and has optical feedback regulation. I have also used it with 2xAAA "Duraloops." I have not measured runtimes.
Has square threads, which I found to be a surprising touch. Nice and smooth. The body is brass, so I guess the black coating is paint. It feels really smooth, hard to grip. No features like a clip to help you there.
The button is a little tough to push, i.e. it is close to flush with the body and offers more physical resistance to being pushed than other momentary switches. This can be a plus or a minus, depending on how you use it.
edit: rule 6 still confuses me, so I'll make this clear: I received this for free as payment for work. They were not expecting a review, and I was not offering one in exchange for a free laser. I don't work for WL, but I guess that is kind of like, freelance work? It was this offer where you email in bugs you find in the website and they fix the bugs and send you a free gift for your trouble. So yeah, I don't think this was a special review unit, but just so you know how I came to be in possession of this pointer, there ya go!
