This PC was suppose to include both a USB Wireless adapter and a USB Bluetooth 4.0 adapter.  The wireless adapter was in the USB port in the front of the computer. But there was NO USB BLUETOOTH 4.0 adapter.  Please send the Bluetooth adapter ASAP.I was very disappointed with the condition of the PC.  I knew it was refurbished but the least you can do is clean/wipe it down and make it look clean.  The keyboard was filthy with actual finger prints on it and the outside of the PC unit was covered with sticker gunk.This purchase does not encourage me to purchase additional refurbished products in the future from Amazon.
