The I-cybies are outstanding for their price. I am the proud owner of Max and Zenni. However they are robots, there is no illusion of life. Not much personality at all, they walk around, go through very limited responses, have a few nice tricks controlled via remote and can display happy, sad and anger (if not enough space is detected to move around).
They do have voice commands, I've never tried it though, should do that one day. You can 'pet' them via buttons and they have pretty basic obstacle detection. They don't recognize faces, or respond the the environment much. But for the price you can't expect miracles.
The walk up chargers take up a lot of room, they work reasonably well. Max and Zenni can usually find theirs and dock after an age of fiddling and adjusting lol.
