I doubt anyone on here will have used it.
Fancy website but I doubt it will be comparable to a mainstream wireless system.
Looks Yale'esque and I doubt 2 seconds is enough to disable any part of the kit but I'd imagine it's one way wireless in any case.
Personally I'd spend your money elsewhere.
Safest way is to enter engineer mode and disconnect the cable fully from the panel end, take a clear photo of the connections first to make connecting back up easier.
As above is the solenoid stuck?
I also doubt anyone
a) takes any notice of the ewd before kicking the doors in
b) if they did they would more than likely chose an old ewd over a new led riddled one.
