Pros: Uses 2 x AAA batteries so cheap to refill
Very well constructed, the casing is made of thick metal with a high quality tough black finish. The battery screw appears to be made of stainless steel with a chrome finish.
The diffraction grating gives some very interesting effects.
The diffraction grating also makes the laser safer as the beam is split into over 100 beams so the effect of any one beam shouldn't damage someone's eye, though it still should not be pointed at anyone.
The diffraction grating unscrews so it can be used as any of the other laser pens.

Cons: The batteries decay quite quickly reducing the brightness of the beam after only a few minute usage.

Other Thoughts: Would be nice to have some different diffraction grating effects to screw on the laser body.

Bottomline: It seems to me to be really well built the case is quite heavy with a very nice black finish.
If you're going to get a laser I would definitely recommend this one.

Pros: Easy to use, Very cheap and very strong. Good for having fun and general mucking around although i dont reccommend unless you know how to be sensible with it. Great Price, Build quality seems good.

Cons: Case for laser doesn't close properly, goes through batteries quite quickly.

Other Thoughts: Great fun and the end diffuser can be removed to allow for a single dot rather than a pattern.

Bottomline: Get this over the True 30mw laser, only a few dollars more and the pattern attachment makes it interesting. (probably the reason why it got through customs)

Pros: makes a really nice effect on a wall, and the dispersion of the beams is probably about 80degrees, so it can cover a large area at not a major distance,
the actual end to it has a decent bit of weight to it, can can be removed to as to use the laser pen - as a laser pen, and the diffraction end can be used with other lasers (if held over the aperture, looks amaising with my 100mW US green)
the beams vary from maybe 30 stronger beams to about 600 smaller beams (both look great in smoke, but the thicker ones look better for photos)
the lasers itself has almost no scatter that im aware of and gives a nice thick beam.

Cons: the batteries supplied (i got 4 - how many did others get) were the epiphany of awful, they last for about 10 seconds before the laser dims, and its only 30mW so thats not right.

Other Thoughts: its a nice laser, and i was thinking, you could market some sort of changing end that utilises various diffraction ends; lines, dots ect, and make the product a bit more versatile.

Bottomline: pretty nice product that im impressed with, might have to get some for people at work and a few of my mates,
