Did not work when it came out of the box

Bought it a couple years ago, it works decently for night vision, but the battery is almost dead after a couple minutes. You also cannot use a external battery pack to power it because as soon an you turn it on, a blue screen comes up and it says MSDC and then shuts off. This is not because of the memory card being too large because I am using a 32gb memory card. The pictures and videos look pretty good, it has 2 night vision settings and 1 daytime. 1-3x zoom, but the 1x making things look bigger than if you look at them with your naked eye, almost like a 2x from the start. Would be way better if it could be powered by an external battery pack because it dies so fast. I would not buy it again, spend a little more money for something from a more reputable company.

i purched this monocular at my local sporting store, price was good but it said it takes a micro sd card for pictures or video but doesn't give a way to format it ,also buttons are side by side and makes it harder to push one button if you have larger fingers

The instruction manual says nothing about formatting card. And when you put one in it says format yes,no press enter but there is no enter button!
