Query: good form factor and speed, poor door design

I bought this adapter because I needed a second port on my laptop, and my coworkers had bought this model.After 6 weeks of gentle use (this stays in the office and doesn't travel), the door on my unit has come apart. It is a very poor design: the hinge on the plastic door (which is integral to holding the cable) is hinged on plastic tabs that wear.I would expect the design to be fragile, but not to be completely unusable in 6 weeks. Stay away...
