I ordered this for my MacAir and it worked brilliantly for viewing photos and videos in HD on my TV. I ordered the cheapest Royal Mail Delivery and it arrived next day! I decided I needed a longer (3m) cable and the product support team were very helpful suggesting I order another, send the first one back and they would give me a refund. Again ordering after 2pm on one day the new cable arrived the next day. I have now got my refund for the first cable, many thanks.
