OVERLY COMPLICATED - NOT FOR THE UNINITIATED!
Well it works, and it has a decent long lead (1.8m I think it was) but for me it's over complicated.
The worst aspect is the ridiculous, unfathomable markings on the various ends, and the related instructions about getting the polarity right.
It's important to get them the right way round, but they make it next to impossible to figure out, and the explanatory diagram is a joke, even if you have a magnifying glass to read it!
It would have been so easy to simply put a big + sign on one side for "centre positive" and a big - sign on the other side for "centre negative" instead of a diagram that would only mean something to an electrical engineer.
If you do buy it, be careful you don't damage your equipment by getting this wrong..
