exelent product, build quality is top shelf. attachment to rail is very strong it will not come off by accident, if you drop your weapon or hit the battery and it comes off you got bigger problems to worry about. im very satisfied with this product. the ony thing i would like to see in the future is a 90 degree USB connection that plugs in to the battery or a magnetic break away that goes to the USB connection like the type c has on the scope itself, this would remove the possibility of breaking the USB port.
