It's frustrating for me too.
I have the flat one, which was the nicest charger I could find that would allow me to use a watch with the Milanese loop.
It's really nicely built and overall I like it quite a bit.
I do dislike Belkin for what they did when they first came out as a "premium cable" company. Back in the day, you could walk into CompUSA (remember them?) and pick up computer cables for your printer or modem for $1.99-$2.99.
Then came Belkin: $24 for the same cables (just a bit prettier - Oh! a gold-plated centronics connector?) and all the cheap ones disappeared because they were designed specifically to be high profit items.
So to me, they are an overpriced accessory manufacturer, the cost of this item pretty much confirms that is what they still are. But again, they sent me a free replacement with no hassles.
