Real junk, such a terrible quality still needs to be searched.
I do not advise you to buy, this is not a robot, but some kind of misunderstanding, add 5-7 and buy more acceptable equipment.
Pros
Price
Cons
Solid shortcomings. This is a child who has learned to walk, but he needs to be constantly monitored, because he can do business and put something in his mouth, curtains, rugs, climb higher to get stuck. Often buggy when sent to the base until you transfer it with your hands. It builds a card and deletes it the next time it is cleaned, unchecking the checkbox to stop sending cards in the application does not help, the checkmark gets back, the base can be searched until the battery runs out. Smaller objects, chair, does not see, table leg, dark object does not see, crashes. For example, he can skip the kitchen and go to the base. All in all I do not recommend buying.
