    Honestly this is one of those items that you hope just works and this one does exactly that. The cables are of high quality and just like other corsair products it has a great warranty.

    This was a good option to buy when price was right but now price increased, there are newer and better products out there.. Yes it is still great product but without any hefty discounts, better off buying something else.
