They do what they say they'll do for sure, but just things like the weight, the feel of them, and around the edge of the socket end on the gold ring its dirty like its old, but it wont come off. Feels really cheap, light and just plastic-ey. But, for a couple of quid what do you expect!
Does exactly what you want it to. Ive had a lot of problem with bad connections from these but this one is good quality and just simply does what i want it to.
Does exactly what it says on the tin! Works perfectly, no crackling etc. One thing I will say is that it should come in a box instead of a plastic bag because mine was ripped and it could have easily fallen out.
