This crap doesn't work lol.  I live in an area that is plagued by suicidal,Emo, Kamikaze, and even Jihadist  Deer (these are the ones that don't run out in front of you, but rather into you!).  Now that Winter is approaching, I haven't had too many opportunities to see how this device interacts with the local critters but in the few opportunities that I have, this product has failed....miserably.
