Review on Cable Matters 2-Pack Retractable Micro USB Cable - 2.5 Feet: Tangle-Free Charging on the Go by Tim Wilson

Very strong. We've had a lot of cables with these ends and had a lot of problems with them, but we've had these two cables and they still work with no problems. The ends aren't loose yet, which is our common problem when disconnecting and reconnecting devices. The end of the USB connector isn't loose either, which is also an issue for the same reason things don't want to charge. These cables seem to last longer as they retract to a more secure position, saving me from having to buy replacement cables frequently.
