It is nice to find a quality product that is readily available at your local office supply store, but I almost want to boycott these stores until they learn to optimize their selection. This pen is available at most of the big chains, and, for the most part, I really like it. The ink does not work on all types of paper; many liquid ink pens are very wet writers and bleed much the same way as a fountain pen can.
Regardless of this issue, this pen pretty much has everything else that I look for in a $2.00 pen. One thing that I did not note in the sample is that I love the look of the ink sloshing around inside the pen, and this is the same reason people love "demonstrator" fountain pens - it is just cool (and useful) to see what the ink is doing inside the barrel of the pen.
I'd say this pen would be fairly agreeable for most preferences, but some people avoid liquid ink pens altogether due to the tendency for the ink to spread on the paper's fibers. At two bucks, I think this is easily worth the risk.
