Customer Ratings

Write a Review 4 / 5 1 out of 1 (100%) reviewers would recommend this product
Reviewer: yibbidy Location: Newcastle, Australia Age: 35-44 Experience Level: Power User Owned Product: over 6 months
Rating: 4/5 Works Great. May 8, 2011 I have been using one of these for several years with Mac, Windows and Linux and it works flawlessly. The only reason it doesn't get 5 stars is because it does not have separate Tx and Rx data LEDs, which is very minor.

I would recommend this item to a friend!
