The best part is that the teachers started looking for the person who had the laser beam, but since this one looks like a pen, they had no idea it was me!

Since then, I've become a school legend...shining my laser light of justice on the chalkboards, or the anatomy chart in health class.


Crummy laser pointer -- DON'T WASTE YOUR MONEY!!!   October 25, 2003

The ClearLine model 2001 is a very lame laser pointer. First of all, it is only rated at 3.5mW, rather than the much more typical <5mW output power provided by other laser pointers. Secondly, it emits a 650nm red beam, which is far less bright than the "bright red" laser pointers that emit at 635nm. You wouldn't think that 15nm here or there would make much difference, but believe me, it does. On the same general topic, make sure to avoid any red laser pointer that emits at 670nm -- they are way too dark.

Laser pointers are a lot of fun, but I *HIGHLY* recommend green laser pointers (emitting at 532nm)over red laser pointers. The human eye is something like 40 times more sensitive to the greenn wavelength than to red, and with a good green laser pointer, you can actually see the beam sslicing through the night sky, which is VERY cool.

Unfortunately, green laser pointers are much more expensive than red laser pointers. If you want an inexpensive laser pointer, try to find a red pointer emitting at 635nm with an output power of no less than <5mW !!! Under no circumstances would I recommend the ClearLine model 2001 laser pointer, however. I bought it, and it is far, far less bright than any of the other red laser pointers I have. You can find much better red laser pointers in the same general price range with a little searching around.

I read all the reviews and decided to give it a try anyway. The only thing that prevents this for being a 5 is the battery cap. It is really hard to remove. I tried two different brands of batteries including energizers and they all worked just fine. The on button has a definite click and feels firm. I did not measure the range everything I do is less than 100 feet. I would recommend this to anyone.

One of the owners had his unit die after a week -- mine died within 30 minutes. On investigation, installing fresh batteries caused so much resistance heating that the aluminum case became impossible to hold -- CAN YOU SAY FIRE HAZARD? The reason for this was that the flimsy spring used to compress the batteries had shifted and lodged against the aluminum case causing a short circuit. There should be a 0.1 cent plastic sleeve to prevent this. This product should be recalled and trashed. I'd send it back -- but I used a tubing cutter to find out what was wrong. At least it won't be re-sold to some other dupe. You really do get what you pay for.


what a piece of junk!   May 6, 2003

After I got it, I put a brand new battery in and it lasted for a loooong 12 seconds and after that it was DEAD. I thought I put in a faulty battery so I replaced it with another new one. Nothing happened. It was really DEAD. Please don't waste your money.
