Pros: - Very powerful laser.
- Visible laserbeam at night.
- Elegant design.
- Included batteries are of good quality.

Cons: - The batteries rattle a bit.
- Laser pen is a bit heavier than expected.
- A bit too bright to use indoors.
- The box is not the same as shown on the pictures.

Other Thoughts: To get the batteries to fit tighter:
Try this with all care or else your batteries can get stuck for always!
Get a sheet of paper and roll 1 or 2 AAA batteries in it so that the papers fits tight. Then cut the paper so that the it goes around the batteries 1 time. Now roll the paper a bit smaller and put it inside the laser, now get the paper to "stick" to the inside so you can put the batteries inside.

Bottomline: - If you're considering to buy a green laser, buy this one. It's really good for novice and experienced users !
*** NEVER POINT THE LASER AT SOMEONE ***

Pros: It's cheap, super bright (got to be more than 5mW) and comes with batteries. The construction appears very solid, and the fit and finsh are excellent. I am very impressed that so little money will get me such a nice product. I can see the beam easily at night or indors if the lights aren't too bright. Will light up clouds at night.

Cons: Batteries that it came with delivered considerably lower performance than fresh Energizers and didn't last very long. Not a big deal though. Also, I would like a switch that is a constant-on instead of a momentary, but that's not what this laser is designed for anyway.

Other Thoughts: This is much brighter than the sku 10094. Also, my sku 10094 didn't last more than a minute before it burned out, even when supplying it with a voltage below spec. Beware that sku unless you want to throw $15 in the trash.

Bottomline: This is a great deal on a green laser as long as it holds up decently. I highly recommend it.

Pros: Man this thing is bright!
Shines really far, and easy to see at night, even the beam.
Came in a nice box with small manual and batteries.
Good size, easy to hold, and has a clip for your shirt pocket if needed.
Uses 2 AAA batteries that you can get anywhere.

Cons: Mine starts bright, but seems to dim A LOT after some use. Output drops as it warms up, and sometimes it flickers like there's a bad connection inside.
Found it cheaper somewhere else.

Other Thoughts: I've read of other people having issues with the output of the laser changing while being used. (Output goes back to normal if I let it sit and cool down for a minute or two once I notice the beam getting weaker). Not really a big deal I guess, it still has one hell of a beam. Lots of friends were impressed with it when we were outside at night.

Bottomline: Want a cheap laser to play with, then get it. Easy to see the beam at night. Even easier if it's smoky/hazy/humid/foggy.
Shines incredibly far. You can't really go wrong here, but don't expect a top of the line laser for $10. No, it wont burn anything.

Pros: - cheap
- very bright; the spot can be clearly visible even in the direct sunlight
- beam is clearly visible at night (perfect for star pointing)
- you get a case too

Cons: - too bright for inside use, also you have to be careful because of possible reflections
- doesn't always "warm up" - usually it takes just a second for beam to begin shining fully, but sometimes you have to toggle it on/off in order for it to start working at the full power
- batteries do not fit tightly and rattle a bit inside

Other Thoughts: - It's NOT a toy. Although it definitely looks fun and everything, you have to be very careful of what you're pointing it at as it can be very dangerous to the eyes
- It's a litle bulky, but I like that (I prefer the feeling that I am holding something in my hand)

Bottomline: Excellent purchase for the price, there are few minor drawbacks, but nothing that doesn't make it that well worth it.
