Having recently purchased this optical lead (albeit the 3mtr one) I have to say this is a superb cable for it's modest price.
When I first got my Home Theatre kit I had to source an optical lead in a hurry, the cheapest lead I could get was a belkin brand which cost £19.99, (from a well known catalouge store) as soon as I saw this lead here for £4.99 I decided to buy it and really glad I did.
The lead came promptly and well packed in a retail polythene package, it looks well made and the cable is much thicker than the Belkin lead I used previously which is reassuring, the plugin connections are not a tight fit and could easily fall out if knocked but this in fairness is not really the fault of this cable and is more about the Toslink design which is a poor design overal in terms of a secure connection.
As the price of this lead is such good value I've just ordered another!
