Query: Excellent product

If your looking at this product you most likely looking for a range booster capable of packet injection. That is exactly what you are getting here with this product. Its light, solid, and most importantly works extremely well for what its made to do. Its not compatible with Macs but odds are your probably going to be using Linux (BackTrack 5 R2), which I run via parallels on my macbook pro. I have had no issues recognizing the card or any other issues at all for that matter.
