My kindle cord has not been charging properly (on off on off takes FOREVER) bought this I already had a USB outlet charger, works great!
Positive Review

Very slow speed, around 1-2Mbps, while I got 10Mbps with another product. There is a configuration tool that you can change parameters (wi-fi channels), but out of the box the card is unusable..
Negative Review

It does not fit my new MacBook Pro 13.3
