I had 1st one for 3 weeks. Wwent and checked and had good piccs etc... but when i went to reset, the screen will light up but no text. I went to FF and returned(not an easy feat for some reason.) I brought new one home tonight after they finally exchanged. Put batteries in, sd card...and same thing again!!! i tried a new sd card, same thing. plus when i turn it on aim, or even "ON" position, it wont shut off either mode. if i switch to "AIM", which tunrs the rted laser on, i slide it to "OFF" and the laser stays on and screen backlight stays on with no letters/#s appearing..... Frustrting...Have 7 D55IR's and even a couple older dig Moultire's with no issues...So far either FFarm had bad batch, or the M80x isnt the cam the others are...
