First things first, I bought this plug to use for unconventional methods (yes, of course to connect XLR to a Jack port, but unusual devices so it could be completely different for other devices). In my situation I was connecting a microphone to a bass guitar multieffects pedal. It does the job, let's make that clear.
The plug feels sturdy and reliable, not too light in the hand which is a good things. I was actually rather surprised how long the plug became when I connected this to the XLR plug on the cable, so keep that in mind when looking for a connector. For some people a hooked connector would work out better.
Overall I am very happy with the product although I do have to add my only real con to the product (keep in mind I'm not sure whether this is for every connection you want to make with it, but for me it was) is that it reduced the volume like 40/60% compared to a cable with XLR on one end and Jack on the other. I'm not sure why this is the case and of course the quality of the sound was the same, but it should be noted that that is what happened.
TL/DR: Good thing, works quite well, could possibly lower your volume depending on how you connect it but is very sturdy and won't randomly break unless you try.
