This kit went well with my question. I had previously replaced the WiFi/BT card with a newer version but decided to try reusing the original antennas. Big mistake. My Matias keyboard and Apple Magic Mouse had poor BT signal strength. Now I have an average of -58-64dBm each. The only reason I gave it 4 stars is because I thought the internal cable could be a bit longer. The instructions that came with it weren't the best either.
