“Mystery” green laser, weapon mountable

Put this in the Mall Ninja category.
For the last couple of years, I’ve been seeing green weapon lasers on eBay and at gun shows. On eBay, they used to go for about $80. Now they can be had for $45. I found a supplier in Hong Kong selling them for $38 and change, shipped.
Gun show vendors still have them at $150+. For purely capitalistic reasons, I bought one from Hong Kong and it arrived today.
I have one thing to say about this laser. MY EYES! OH MY EYES! This thing is freaking bright. View image
On the left, the green laser. On the right, an Insight M6 that I carry on my Glock. The camera is not so good, but you can clearly see how INSANELY BRIGHT the green laser is.
It comes with 2 mounts. One is a barrel clamp, the other is a rail mount. Both mounts are clamped with hex-head screws and all the hardware (including hex keys) is included in the box.
It also comes with 2 switches. One is a pushbutton switch like you would see at the end of a tactical flashlight. It is on/off, not momentary. The other looks like a standard pressure pad switch, but mine has a rocker-like function. Push the top of the pad and it clicks on, push the bottom of the pad and it clicks off. I don’t know if this is by design or if I just got a flakey one.
I have no intention of keeping this laser. As I said, I bought this for purely capitalistic reasons. There is a gun show this weekend and if those dealers are still selling this laser for $150, I’m putting a sign on my backpack that says “Green laser–$100″ and see if I have any takers. If not, then I have a blindingly bright laser that also happens to function as a flashlight. Seriously, this thing lights up a room like you wouldn’t believe.
If I happen to keep it, I’ll be interested to find out how well it keeps a zero.
