Only complaint is it does not want to stay tight to the my night shadow unit ince mounted. This may not be all bad because it actually gives me a little adjustment room for storing the night shadow in its case since I dont remove the ATN 450 after use. Oterwise, the unit does what I expected - adding more IR light to the binocs.
Pros: easy to setup, adds more IR light tahn the built -in
Cons: wobbles when mounted
