This replaced an original buckle strap on a Citizen eco watch. The watch looks very good now, much better I think.  Also, just pulling it on is quicker (instead of buckling) so I wear it more often.  It caught hairs on my wrist at first but that soon abated. Connecting the band is easy with a small screwdriver.  Adjusting the length was not too difficult following a "how to" on the web.  However adjustment does require some detail work, tools, and patience.

6 month update: strongly recommended.  This is a great band, very comfortable, still looks new.  I wear my watch more often now, practically daily, than I did with the original buckle band.
