Okay, so it's actually NOT solderless (thanks SD for the misleading advertising) as you have to join up some of the wires together to make it work. Took me a little while to interpret the instructions and make the thing work, but once I got it, there's nothing wrong with it at all! If you're good with a soldering iron and are prepared to stick it out, I'd probably stay with that, but if you want something a bit quicker and less fixed for later changes, I wouldn't sneeze at trying out one of these!
