thought of weather sealing to them. They even have a phone jack port
that is wide open to the circuit board and begging for water to enter.


Also not a fan of the Radiopopper JrX transmitter hotshoe connection. It doesn't clamp or fasten in any fashion. You slide it on and it tilts down to sort of "lock" on, but if you bump something it could easily com flying off.

That's handy info to know. I've never gotten my Cybersyncs near water, so I'm not sure how they'd perform under the same conditions--but I don't think there is much weather sealing to speak of. I have five receivers and two triggers, and all have performed as expected during my usage. I've only had two minor incidences:


1) My 50D fell off my lap when I was crouched and landed squarely on the antenna of the CST sitting in the shoe. The CST split at the seam. I snapped it back together, and it's worked fine ever since (although it is slightly scarred from the ordeal).


2) I dropped a receiver onto pavement from a height of about four feet. It landed on the bottom corner. After picking it up, I realized it wasn't working. I opened up the batter compartment to find a battery contact was smashed so that it was no longer supplying tension to the battery holding it in place (and maintaining a circuit). I used my finger and bent the contact back into place. It, too, has been working ever since.


Whatever system you go with, make sure you have more than you think you'll need. Any system can (and will) fail eventually, and it's always good to have backups (as well as fresh batteries).
