Rayfoss's Cheaper Lasers' Quality

I'm interested in getting one of these two lasers:

30mw 532nm Rayfoss Waterproof - $30
50mw 532nm Rayfoss Pointer - $26

But I figured I'd ask for you guys' opinions.

Are these good lasers?
I read the guide and Rayfoss was on the better list while still having pretty cheap lasers.
50mw for $26? That sounds good to me, but is the quality good enough?
And for the first one, that battery isn't going to fit it any of my standard AA or AAA charger, is it?
What about a duty cycle?

This isn't my first laser, I had a 5mw Core for a while, but I lost it somewhere and I'm getting something more powerful. Any input is appreciated, thanks guys!

I have the 100mw waterproof and haven't had any problems with it. I doubt there's anything "wrong" with either of those.

dude his question should be are they up to the power they say
