Just installed the Blink Outdoor 4 mount kit and here's my honest take:
The weatherproof housing is legit - survived a thunderstorm without any issues. Night vision works perfectly through the cover, which was my main concern.
Installation was stupid easy. The 360° swivel is nice, but heads up - once you tighten the nut, good luck readjusting without loosening everything. Learned that the hard way when a squirrel kept triggering my motion alerts.
The outlet mount for Sync Module is genius! Cleared up so much counter space in my garage. Though why they didn't include a longer USB cable is beyond me - had to dig through my junk drawer for one.
Pro tip: Set motion sensitivity to 3 unless you want notifications every time a leaf blows by. Battery life improved dramatically after I adjusted mine.
Wish list: Color night vision would be killer, and adjusting angles post-install needs improvement. But for the price? Definitely worth it for basic home security.
