they are hit and miss. some work great and others dont . i have one that is not doing a great job, but i hear the company is good and fixes problems one thing that people tend to forget is that a cam is used as a scouting tool. i do not postcard type pics...i need to know what is there. a common problem with the stealth cam in centering the subject. u get alot of butt pics. i am looking at the deer cam with the olympus camera in it. $130 and i hear that it is great. u can get almost 3 stealths for that. my stealth is showing pics are taken, but there is NO noise when the number changes...who knows good luck
