I got my picooZ about 2 years ago as a present. I used it a lot then totally forgot about it for a year. Now its a permanent resident of the office where I work and I'm still using the original batterys in the controller. People complain that it isnt easy to control... its not the case.. persevere with the setup and take into account that you have to adjust how you control it depending on how much charge is left in the little thing.
Amazing fun and 20 minutes charge isnt a lot considering how long the charge lasts, how small and simple it is and how little it costs.
Id recommend indoor use only (even air conditioning ducts blow it all over the place)..
Excellent fun.
