GibH one different that original better quality and gold plated, simple connectors works ok, but they are far away from the quality, one way to use original gold plated pins in the simple one. take off from both connectors pins and see what is the different. I pass this problem with some pain, some cheap are very bad, with loose pins, expensive gold plated like original never saw where to get. so I use cheap but not tragic. good luck in founding normal quality, but if you will get somewhere like original let me know where. thanks Stasys
