These work perfectly fine in all the HUGE variety of devices I have with USB2 MicroB ports.
5 x Mobile Phones. Android. BB. etc etc.
My Wireless Mouse (recharging), External Drive bays, an Amazon Kindle, a WiFi 3G Router and so on...
Basically this is the quintessential USB MicroB cable.
Nice and long too as most such other cables are only 500mm and cost much more than this.
Reasonably Rugged as well, the moulding is formed nicely and both connectors slide and fit in firmly and tight.Rating: [5 of 5 Stars!]
