First negative review I have seen interesting.  The ones that aren’t a year old yet if you are having issues call tactacam.  They have a 1 year warranty.  I have 7 and just added 2 more.  I don’t leave mine out all year. I only run them from August to November.  I update the firmware each year after I pull them in if there is one available and remove the batteries.   My oldest is about 15 months and is still humming right along.   I have had to toy with the sensitivity on a few of them.  If these flake out in the coming years I might just stop running cameras all together.
I switched to tactacam from Reconyx. It irritates me to no end that Reconyx makes you pay for 6 months of service each year or you are forced to purchase a new SIM card.
