I buy refurb items when ever I can.  The reasoning is:1-The price is less2-Each refurb item has been tested and certified to work.3-Refurb items have the same accessories as "new" itemsApparently with this keyboard from TRG, items 2 and 3 are not the case.  I received the keyboard in the expected time frame and the unit looked new.  Missing was the extender, batteries and documentation.  No real issue, however my problem is that this keyboard clearly was not tested.I saw a reference to having to hit the keys squarely in the middle for them to work, I saw another where the "c" key didn't work.  On my "refurb" from TRG the :c, 5,0,h,b and n keys didn't work no matter where you stroke them.  Clearly this keyboard is defective.I like the keyboard so I am going to buy a new one.  I will upgrade or downgrade this review based on my next one. 

Question: How is the unit?
Answer: the unit looked new
