Hexbug Inchworm Micro Robotic Creature that You Control

My daughter and I review a small robot we bought from Walmart. The cat watches from her elevated seat. The Hexbug robot is battery powered with AG13/LR44 batteries, included. It will be a pain when the batteries die and need to be replaced, since they are an odd size battery and kind of expensive. My daughter really likes the remote control, which also uses AG13/LR44 batteries. The package says this robot is for people 8+, but my daughter is 6 and likes it just fine.
