Basically it's a copy of a standard crtridge carreir a-la-audio-technica. Fit is good but not perfect, wiring is good enough.
Important to not is it's sold without screws so be sure to have your own. So, in a nutshell you get 80% of a standard carrier for 30% of the price. Whether that is a good deal is for you to decide... but if you are already looking into cheap carriers, this is about as good as it can get.
