I bought this on the basis of price & reviews saying it worked fine. First impression was that it looked cheap and also found that the short cable meant that I had to sit on a footrest to play, but thought I could live with that.
Then I found one of the shoulder buttons was inclined to stick on. Kept calm and carried on.
When all of the buttons refused to function in rather less than a month, the awful piece of tat that I'd forked out good money on described a gentle parabola on its way to the bin.
Don't be fooled. It's cheap, looks it and breaks (and I didn't treat it at all roughly). And its cable is too short.
