The Tyco Cyber Shocker product was 2005's sleeper hit. A battle robot/tank that transforms into a bowling ball sized attack vehicle, it is remarkably robust and flexible in terms of its operating capabilitiies. Fast moving, with hard wearing parts and excellent battery life. Initially, the product was sold without battreries and recharger for £79 and that put people off. Later repackaging included the battery and charger with Amazon selling the unit off at £39, making it the bargain of the year compared to Robosapien's staggering £200 price tag.
