First of all, I am unhappy with its batteries. They last for one week at most. I think they
should last at least one month.
The quality of this robot is not up to standard either. A good robot should only need checking
every eight months. My robot has already stopped working completely. I don't know what's
the matter with it.
I regret having bought a robot like this. You'd better send me a new one, or I would like
to get my money back.
I hope to receive your reply soon.
