there seems to be zero internal battery there's a hole in the side of the case but there doesn't seem to be anything inside it for a microSD card I was really hoping for a DVR but it seems to be missing I also recommend buying some battery extension cables there's only a small piece of velcro to attach the battery to the Head strip and if anybody has any information to the best battery to run this monitor on I would much we appreciate it there is very little literature for it

Almost perfect, a very very good display, easy to use, good design, good radio reception what more can I say. Documentation reduced to the bare minimum. A sun visor as an accessory not very well designed. connections a little cheap finally some details that can be adjusted by the manufacturer quite easily. A dvr would have been a plus. An unbeatable quality/price ratio I recommend this product.
