Summary: Fisher Quad Multipen
Comment: First, there is a mostly-negative review of this pen from someone that did not like the Fisher ball-point ink. You either like the Fisher refills, they allow you to write on more surfaces, higher temperature range, etc., then other refills, or you do not -- they do skip more, particularly on first use, and they generally don't have the flow of say Lamy, which is generally the top refill in this category. I should note that Lamy refills do fit fine in the Fisher, so if you prefer those, and easy remedy.

In general, in terms of the Fisher Quad pen, it is a very well made pen, and an exceptional value at it's current price point. Advantages include:

* Rubber Barrel (easy to grip)
* Chrome finish below that, in high wear area
* Very good upper Barrel in a sort of grey/titanium type finish
* Better side release mechanism (many have plastic clip release)

I found the pen somewhat lighter than the metal Lamy 4-in-1 variants, but to have better heft than a lot of the cheaper pens. Make no mistake, the Fisher is very well made. The Stylus is quite functinal. The inks, once you get used to them, quite serviceable (and easily replaced with Lamy if you don't). The mechanical pencil is of the 0.5mm class. One of the top 4-in-1 pens at any price point, and an exceptional value at its current one.

Summary: One great pen!
Comment: This is the best pen that I have ever purchased, it is really a great product. I am completely satisfied. It does exactly what it says. I had trouble figuring out where the eraser was, I was afraid of breaking it. The directions were not clear to me. You pull the button on the end of the pen.

Summary: What a great pen!
Comment: Excellent pen if you have a touchscreen PDA/Smartphone. Being a 'Space Pen', it writes in all positions without running dry. It's nicely 'thick' for those who like that, and its of high quality.

Summary: good intentions
Comment: I was excited when I ordered this pen online--I thought that I could finally put away my separate pen and pencil. However, I was greatly disappointed when I actually sat down to write with it. I would compare the quality of the ink to that of a Bic ballpoint pen. The ink doesn't "flow" like a Pilot pen. Maybe the cartridge that came with the pen is a dud. I'm going to give the pen one more chance by ordering a refill cartridge and seeing if that works better. Who cares if it can write upside down and under water? I just want it to write decently on dry land.
