I don't normally write product reviews just because they work, but last weekend I almost tore my hair out trying to debug a project because I bought two built-in connectors . years ago were wrong. So I'm happy to report that all 6 of these tests passed flawlessly and the two I've commissioned are working flawlessly. Doesn't guarantee every one you've ordered will work, but my experience has been a lot better than two I bought a few years ago that were 0 for 2!
