Review on Enhance Your Lighting with Bioluz LED Halogen Ceramic Connector: The Perfect Solution for Efficient Illumination by Duane Mejia

Of course the price was very low so I shouldn't complain and the two I've installed so far work but I had to spend 10 minutes trying to find one repairing the two I used. The spring clip that accepts the pin from the GU5.3 bulb is very thin metal and one didn't have its top bent properly so I couldn't insert the bulb pin - instead it started squeezing the metal clip. I had to disassemble the part and use tweezers to adjust the spring and bend the clamp again. It might have been worth just using a different one, but I've already soldered it. Bottom line, they cost 80 cents for a pack of 10, which is incredibly cheap. If the pair isn't perfect, I probably shouldn't complain, but so far I'm only 50%.
