I THINK THEY ARE GREAT CAMERAS, I HAVE THREE, MY UNCLE HAS TWO, AND MY BROTHER HAS ONE AND WE HAVN'T HAD ANY PROBLEMS. WHEN I GET OUT OF MY TREE I AM ABOUT 45 YARDS AWAY AND I CAN SEE THE INFRARED LIGHTS ON THE CAM GO OFF INSTANTLY. THE BATTERY LIFE ON THEM IS ALSO PRETTY GOOD USUALLY 1200 PICS PER SET OF BATTERIES, BUT I HAVE HEARD OF SOME CAMS GETTING A FEW LESS. LET ME KNOW IF YOU HAVE ANY MORE QUESTIONS I'LL ANSWER THEM HONESTLY.
