Average value of each feature
I bought this pen four years ago and it has served me well.

Pros
- Relatively light weight for everything that it is.
- Laser pointer is very visible in medium light from across the room.
- LED Flashlight is effective in very dim lighting for about 9 feet.
- Ink has never refused to write on any typical surface.
- The clip STILL hasn't broken off or bent (That's record for me)
- Stylus is soft enough to not scratch my screen.

Cons
- Batteries have a short life. I spent $12 at Walmart to replace the four batters each time, until I found four for $3 on Froogle.
- The buttons get pressed too easily accidentally. It is common for the laser point to be running for hours until I notice it in my laptop bag.
- Ink is short lived but not too expensive to replace.

Belkin QUADRA 4-IN-1 Pen, Stylus, Laser Pointer & LED light
This pen has a laser, led light, stylus, and ink pen. The pen performs as advertised. Nits...When placed in your pocket the 2 buttons can get pressed which will activate the laser or led and can run the battery down. An improvement would be to a have a slide switch to turn these buttons on and off or perhaps the button activation pressure could be stiffer. I still carry a PDA and use the stylus tip with it. The pen is a little long for many shirt pockets. Buy extra betteries as you will need them. There are multipacks available here at Amazon. Buy them here because otherwise they are expensive. My cat will chase the laser beam :) Overall a very good product.

Very cool! Great for any computer geeks in the family!
I will admit that I am somewhat a computer geek, and so when I received this as a gift I thought it was very cool. I then ordered one for a friend at work who absolutely loved it. He probably liked the laser pointer the most because it gave him one less thing to carry to his meetings, and it came in very handy at times. This pen is very light but seems to be quite durable. The pen is easy to refill, as are the batteries for the laser pointer and flashlight.

It makes a great gift for any geek you may know. :)

Nothing else like it!!! Awesome tool!
When I first got my Quadra almost 5 years ago I played with the laser all the time like a kid with a new toy. The lasers' intensity became dim as the batteries wore out during the first 2 weeks that it never left my hand. Imagine my embarassment when someone asked to use my gadget in a meeting and my batteries were spent. After that I found cheap batteries online. With normal use of the laser and multiple daily use of the LED light a set of batteries will last 3 months or longer. Later I bought spare ink cartridges. They are standard and last for approx 20 pages full of writing. More than most students will do quarterly in this age of the PC. I bought 8 of these for gifts. Only 5 made it to others and I've kept 3 as spares. I keep it clipped to the front of my button up shirt with half in and half out. The buttons never get accidently pressed after you become aware of where not to grab it when removing it from your shirt. I have used stylus type PDAs for 9 years and so all the more value to me. There is no other similar product to compare this to! I've looked. My only complaint is that when you replace the batteries you need to make sure the buttons are facing down so they don't get jamned up and not work properly later. Oops. Another complaint is that these style of ink cartridges don't seem to write on every surface. OEM or German manufactured. They always work on writing paper, but some glossy papers or smooth surfaces (bathroom wall tiles) will not provide enough friction to turn the rollerball. Also, learn from my mistakes. Don't be tempted to entertain children with the laser. They will cry until you let them play with it. After they point the bright hazardous laser light into the your eyes, their eyes, and the eyes of other children and adults, you won't be popular with anyone. :-) [...]
