Exchange or Keep? What to do????

I purchased what was supposed to be a Used: in very good condition  SanDisk Sansa Clip + 4GB MP3  with arm strap and charging cable but instead received a Sansa Fuze 4GB with arm strap and charging cable from an online retailer.  It appears in very good condition, but how do they rate in value?  Is it worth returning, or a blessing in disguise??? 

I’d keep it and be thankful for the error. The Fuze is a better/more featured player than the Clip+.

It has a larger color screen so you can see album art and you can also convert videos and watch them on it.
