I just found out about this product. Seems like the product is really inexpensive and doesn't sound like it would work in theory. But has anyone had any personal experience with it?
Sure it'd work. L-com sells a bunch of Wi-Fi splitters, although theirs have N connectors and are for outdoors or in-building DAS deployments. Also, SNB uses octoBox Wi-Fi splitters to reach the "peak" throughput results it shows in its router reviews. So the technology works and isn't really new.

You'd need to calculate your link budget. Let's say you have an RT-AC66U and get 22.7 dBm transit power on chain 1. Splitting that 4 ways is 5.675 dBm, less a bit more due to insertion loss. Then subtract the assembly loss for your coax. 50 feet of RG-6 is 7.9 dB. I assume unity gain for simplicity because I don't know what gain applies to their antennas. Anyway, your RSSI would be as strong as 5.675-7.9, or -2 dBm, which is extremely high. 5 GHz would naturally be weaker, by approx. 5 dB, but still very strong. You might try to do this MIMO for even better results, but on the face of it, the attenuation would be negligible in any case.

I hadn't noticed that they started selling these after the crowdsourcing fell through - thanks for the heads up.
