I have had good luck with Muddy and Tasco , but others report they are both trash . I had one Tasco that was a pos out of the box , took it back to Walmart and got another one . The second one worked well for a $30,00 camera .
If you figure dollars per year it's tough to beat those Walmart Tasco cameras.
I get anywhere grom 3-5 years out of one, for $30 bucks.
They are good for long trails or feeding spots but don't have the sensitivity or trigger speed for scouting situations.
