I know folk that over analyze such things, I don't. I get this, plug it in and it's done.

My laptop doesn't have Bluetooth capability and I like to add the feature to use with a Cricut crafting machine.
Any help will be appreciated as the Bluetooth adapter is a gift for my crafting wife's new machine.
