I had an M60 for 4months which I sent back because of white out in the flash pics.
They sent me a new I40 replacement after 3weeks of going back and forth. 1st night I put it out over night on a corn pile and the IR pics were so grainy that it was horrible. I couldn't keep the cam just based on day pics (which were crisp and clear) and battery life. I sold it on craigslist the next day for the price I paid for my original M60. I used the money to buy a Scouguard.
That was 2yrs ago and will never purchase or recommend a Moultrie product again.
