Trying a $500 item to see if you will like it is not the kind of test Jerry is speaking of. He is talking about troubleshooting, not product reviews. These 12V kits are a little Red Flaggy when only sold by Walmart, Ebay, alibaba and Amazon
They are also sold with good reviews from Speedway, Summit, and other automotive sources.
You can find negative reviews on Amazon or Ebay for anything.
Given Jerry's discussions of buying and testing various distributor options, or engine component options, I would say that this is exactly what he proposes. Build a system using the components that you think should work and see if it performs the way you need it to.
Either way, Martin expliclty asked if anyone has experience with the electric units because he already knows about traditional setups, so we should probably get back on-topic before we get our hands slapped.
Edit: You appear to be under the impression that this was a random purchase on a whim. All electric AC systems for cars have been used for ~20 years now and between economy of scale and improvements in the technology, this is an entirely plausible thing to build and have work. A great deal of research has gone into this decision
