I used one of those (similar model, definitely the same brand) with some generic bookshelf speakers for a very short-lived design project last year. The connectors are EXTREMELY flimsy and broke off in transit — in fact, the whole thing is cheap plastic construction, very much hobbyist-DIY quality (ie. not good enough for serious listening) and won't last long. It may work out okay for a while but be sure you can easily return for a refund, that's all I'm saying. Consider investing in proper gear rather than buying $4 worth of parts in a factory-assembled $25 package.
Or if you want something comparable but just a little bit better, have a look at
this.
