    • didnt work for me

      Overstock states this adapter makes any mouse bluetooth. NOT! I believe the computer must be Bluetooth ready or have it built in. Mine does not so I thought this adapter would make a wireless mouse Bluetooth. Then perhaps my wireless mouse was optical or RF frequency or....whatever. I'm still not sure why it didn't work.
