I was pleased with this key, I own for two years. But it broke very strange way for a supposed key to be foolproof and that I do not do heavy use: the gap between the port and the PCB dropped. Opening the rubber that surrounds the key, I found that this weld is very fragile reality, nothing holds more port and PCB outside of the rubber.
In short, a key "traveler" who does not keep its promises into reality.
