Not a bad piece of iron and really always comes with prey. Can be used as a camera on wheels, there is IR illumination. To maintain cleanliness on a regular basis, it’s quite, but you still need to understand that the format of a rounded pancake will not allow you to visit difficult places. Also, before launching, all the srach from toys, socks, shoes and other things must be removed =) Progress does not stand still and it is just fine to use its benefits.
