Well, what is exactly wrong with it? Is it just the fact you cannot put it back together?

It rather looks like one of the diode pins has come off the diode if that is the case there is a 99.2% chance that you can not solder it back on and you will need a new laser diode.

It looks like non standard Chinese BS, any laser should be easy to focus except for pen types that are fixed focus.

I agree its way better to assemble a laser yourself so you know what's in it and how its put together. For some examples of how to easily assemble a laser see the white links in my signature.

I guess the pages on Amazon change sometimes but DTR still sells some things on Amazon DTR's Laser Shop @ Amazon.com: but you can buy anything he sells from his web site https://sites.google.com/site/dtrlpf/ The Osram PLTB450B is different from the 9mm but is also a good choice.

are the 3 element lens or g2 focusable?
and I'm guessing the g2 lens is better than 3 element?

Yes they are focusable, you screw a focus knob on the end and they screw directly into the module in front of the diode.

And yes the G2 lens is better.

It comes with it. Extended barrel will just stick out further. They were mainly designed for custom focus rings to match how far the three element threads stick out of a module wen focused so you can swap between them without having to adjust the module position.
