back up and it should start swimming again. nope. no response at all. light tap? nothing. firm tap? nothing. in order to wake it up, i had to pull it from the tank, press the 2 buttons, place it back in - 3 minutes later, the cycle repeats.
dying batteries? nope, replace with brand new - same cycle: swims for 3 minutes, dead, pull from water, press buttons, swims for 3 minutes.
headed back to target to return - hope the replacement works better. very disappointing - but at least my son gets to learn about customer service...and lack of quality control.
