is there any difference between sparkfun pro micro and arduino pro micro?

thanks mega_mozg,

the reason I ask for the sparkfun pro micro is the one I get from ebay:
http://www.ebay.com/itm/New-Pro-Micro-AT...i-/140972980117

does not have "sparkfun" in it.

so since I know almost nothing about electronics,
I wonder if it is the same product or not.

I have googled this, and find out that sparkfun is a brand name.
And the one from ebay is a chinese clone.

so I guess it is the same, but I am not very sure about it.
