These poorly-designed adapters have a history of shorting out and catching fire. Yes, I am surprised that anybody would think "looks nice" is a more important feature than "won't burn our customers' houses down".
Can you point me to cases of houses burning down? I've no doubt it's possible, but lots of things are possible. I got a small flame from mine when it burned out but it was short-lived and would probably have had to have been sitting in a basket of tinder to cause any serious damage to anything beyond the cord.
If that is indeed a problem then that’s a problem. I don’t know. Stats?
