I am quite fond of Apple products, but i'm not an idiot, if someone else offers the same thing for half the money, you go for it. Apple doesn't do an HDMI cable, but if they did, it'd be several times as expensive as this one, and do exactly nothing that this one doesn't, so a smattering of stars for that.
Also, Apple's customer care often leaves a little to be desired, but when my original ordered cable turned out to be a dud, i contacted the seller, who almost immediately replied with detailed instructions on how to proceed. Meaning i got my replacement within 2 days.
Shipping was very fast, it arrived about 4 days before the earliest estimate, only 2 days after the order was placed! so my replacement cable managed to arrive before the original should have?! Can't fault their logistics people.
Overall the product is great, i get some wierd 'no signal' static every now and again when it's first plugged in, but i think i've marked that down to the odd mix of monitor -> Laptop i've got going on.
The only reason it isn't 5 stars, is a little niggle that the cable it's self isn't very flexible at all, i'm hoping it's just because it's new. It's a tiny bit irritating due to the layout on my desk the cable sticks out into the middle. Grr.
AND more importantly, if something is wrong with your original, rest easy, this seller is great at speedy replacements :)
