Very low-cost way to join Cat5 cables – RJ45 Network Cable Extension Coupler Reviews

Very cheap ($), seems well-made enough.
The contact pins aren't gold-plated. And since most RJ-45 plugs have plated contacts, this opens up the possibility of galvanic corrosion (key word: POSSIBILITY), which might lead to signal degradation.
I've seen similar couplers in stores selling for *MANY* times more, though these were "Cat 5" rated and had plated contacts. I wonder whether these will work reliably in a gigabit/Cat6 setup.
While I recommend these (especially given the asking price), I'd be wary about using them in the long-term, especially in humid environments, and/or with very long (combined) cable runs.
