Review on Ethernet Crystal Connector Plated with Postta by Johnny Black

The main complaint is that they don't come with a charging rod, which requires extra time and care to get good results. and all contacts work fine, no problems that some other people claim. With UTP Cat6 AWG23, the shell hardly fits into the connector, so you can easily install S/UTP. But I think SFTP is out of the question. Not to mention that it would be very difficult to foil a twisted pair without a load rail. BTW the plastic clip isn't as strong as I'd like, it stays in place well but is likely to be prone to breakage and doesn't have the satisfying "CLIP!" of other connectors you may find. Overall, I'd recommend going elsewhere, if only for boot strip connectors. but if you charge by the hour and don't mind breaking your fingers, go for it.
