I purchased this at Walmart for a similar price.  I took it home and started messing with it to get rid of one of the links, as many people have had issues with.  I used a regular pin to do it.  This wasn't the ideal tool, but I finished adjusting the clasp and removing one link in about 15 minutes time from start to finish.  The pins are spring loaded, so all you have to do is compress the one side and they come loose.

About the watch...I love it.  I really do.  Reason is it is very simple.  I am not one that is going to be using all of the features.  I want something that is durable, tells time, and I don't really have to worry about.  With the atomic time and the fact that it is a g-shock, I am anticipating many years of daily use.  I wear a suit for a living, so I won't be landscaping or bricklaying with it every day, but I find I am rough on just about everything I own.  The seiko I purchased for the same price broke in 2-3 weeks, so I wanted something more durable.  While this dress is FAR from formal, it is shiny enough to work with a suit.  I am not a "watch guy".  I just got tired of depending on my cell phone for yet another service.  I love my phone, but am tired of using it for everything.

The only reason this doesn't get 5 stars is that the 2 closest links to the watch case are plastic.  Not sure what is going on there.  Feels like I could break it with my hand, but the reviews say otherwise, so I'll trust casio and g-shock.
