every now and then one will fall over if you shoot from the right angle and close enough with smaller plate(less weight) and the moon and stars aligned right ect.
Not really a problem for us really we only shoot a plate a few times before repainting it. Only takes a few seconds to run down range on a 4 wheeler.
You can also hang a chain from the same stand with a hook on one end to hang milk jugs up.
