Excellent value for money if you are looking for spare parts or maybe building your own instrument!
With that said, they do not look very "cool", but they are not ugly either. The screws are maybe not the strongest or thickest, but they do the job. I used mine on an old Ibanez bass that is not exactly a high profile instrument, but that I still don't want to drop while playing. Buying these was a sensible option - and, as it turned out, the right choice for me.
If you are looking for something of "the right" brand, something with "the right" looks etc, these may not be for you. But if you, like me, are looking for something that will do the job without costing you an arm and a half - buy these!
