I've got a couple of the cheap Muddys. I've been relatively pleased for the price. Not sure how many MP's, or IR's or anything else. I was in a Rural King in the fall of 2018 and there was a bunch of 'em for $25 each. Couldn't pass that up.
I have a bunch of Moultries and the Muddys operate just like Moultrie's. When you push the SD card in, it flashes with % battery life, and does a countdown to let you know it's ready. Or, if the card has an issue, it flashes error, or just doesn't count.
Here's a couple of pics from one - same spot, different lighting.
