I already had these (included) but after a few years one of the small tips broke off. Make sure the screws are tight. If they come loose, the parts will be subjected to extra stress and may break. For installing Bose speakers, this really is the best option. One of the reviews mentions that they have tried using them with other speaker brands and I would be wary of that. Bose makes good things, but they also tend to make things that only work really well with other Bose products. It would be nice if Bose sold some of the smaller parts that are easier to break, but buying from Amazon is a good second choice.
