Nicely made laser
Can re-use the lens for other lasers / purposes
Nice metal housing
Can get a reasonably fine focussed line
Price !!!
The inner focus mechanism isn't particulaly tight. If you over tighten the outer ring, the inner can loosen up. Nothing a bit of PTFE tape won't solve if this happens.
Can be a bit bright for close up work
If you do mess up the focus, take off the outer lens by unscrewing the metal ring, take out the inner plastic lens holder and wrap with a couple of turns of PTFE. Apply power and focus the inner lens until you get a nice sharp dot a the distance you're intending to use the laser at. Then carefully screw the outer lens (which gives you the cross) back on and everything is fine and dandy again :)
Don't dither - its a good laser so buy one !
