The battery capacity is too small, but it's not a big problem now that there is external charging.The maximum aperture is only 3.3, which is not as good as my mobile phone Z1. However, even if the 3.3 background is blurred, it is OK. The price is there, so you can't ask too much.Signal problem, too many WIFI signals will interfere, making the picture very stuck, but this will not happen outside
summary
It is a novel product. The design concept is easy to carry and operate. If there are too many requirements, it will exceed this product
