How big is the USB dongle? and is there a bluetooth version of this keyboard?

The dongle is about one inch long with about the normal size for width and height of a regular USB stick. It has no Bluetooth, but who needs it. The main reason I got this set is the AES wireless encryption. At least you know that hackers can't use a wireless dongle sniffer to track your keystrokes with it. With Bluetooth keyboards they can sniff everything (usernames passwords, banking info, emails, etc...), that is bad!!!

I need replacement usb tab for ms5050 keyboard..lost it. ms part #c938881-01

Each USB tab is married to that particular key board and mouse it came with, once lost or bad it can’t be replaced. Sorry but your keyboard is unusable now.

How is this different from PP4-00001?

They are very similar, just a few cosmetic differences.
