My daughter has always wanted a robot dog and finally got one for her birthday. It's great, easy to charge (and fast enough), mostly easy to control. She is 7 years old and almost immediately got the basic moves she wanted. I know he can do more but we haven't explored that yet, she loves what he does with a simple remote control (dance, walk, do hand commands). Not sure if there's a volume control, but it's not loud at all, which bothered me because of the other robot dog options. Perfect for ages 4+ for the price and convenience.
