I was looking for a bluetooth key to use my two PS3 controllers on pc wireless. With XInput Wrapper program, I play games pc using one key for both wireless controllers lying around and keeping my distance from the screen (about 5m). The controllers are connected in a second. To know: there is a blue LED that indicates the status of the connection. Personally, the key is behind the tower (and there is no interference whatsoever with a bluetooth headphones that I use while I play or wifi in the box to within a meter of the tower). So I never see that light. For over a month I have no problems to report. I recommend.
