Eeeek, there's a thread on here from a few months ago about these being massively under spec - I can't search from the mobile app otherwise I'd find the thread. But maybe someone at a PC can do a quick forum search.
If memory serves, this poster had to file an ebay dispute.
Sorry - it was the similarity in naming scheme that brought this to my attention, but now that I'm at a regular computer to search a bit, I can see that this is a different seller here. The module I was remembering complaints about was this: Industrial DIY 150mw 532nm Green Laser Module Spring [Moduel] - $40.99 : wlaser
That said, if this is IQS, I'll add my own experience with them:
- Ordered their #200 green, died after 3 seconds of use (IR went LED)
- They sent a replacement. Crystals weren't aligned, power was ~100mW and unstable. Died in a few weeks.
Looks like a deal worth giving a shot. If he has these for awhile I might give at least one a shot. I need a high power green module for the last piece of a set being built.
