I have a drawer full of batteries on hand for those meltdown moments when my tots favorite toy goes kaput. But that drawer gives me such guilt – all those used batteries are leaking toxic destruction in our landfills! And it is not fair to the younger generations that they are unknowing adding to the problem they will inherit. Ecotronic is a new line of toys that do not require batteries, they are wind up toys that have all the bell and whistles of any electronic toy! Not only are you teaching your tots eco-responsibility but you can avoid those meltdowns when batteries die AND save on batteries!! A definite win-win-win!! The Rocket has flashing lights and sounds for $24.95 and the Microphone has flashing lights, percussion sounds, music, applause, and realistic amplifier for $19.95. Both available at Growing Tree Toys.
