The product looks fine, but it shipped as a 3 pin and I had requested and assumed I was getting a 4 pin, so I cannot use it to test it anyway. The website indicated that it was a 4 pin, but the communication post sale has been a little difficult to understand and I am not sure whether they are intentionally stalling or genuinely do not understand the issue. Either way, I think they want me to buy again to get a 4 pin however I have no confidence that they will send the right product. I would not purchase from them again. This mistake has almost cost me $100 AUD in the end.
