So far, I can't find anything wrong with this starter kit. It has met my expectations and provided me with the groundwork to creating my own little robot empire. It is simple enough to understand without the need for an engineering degree. Unfortunately, I can only give it 4 stars because it does seem to mislead a bit on the BASIC Stamp issue. You must buy a BS2 - IC or compatible IC before you attach a serial cable and start coding commands for the little guy. Although simple to setup, the price of the BS2 chip costs as much as the kit itself and will quickly eat away at your budget depnding on where you find it. The robot included is little different from a prototype for the Friendly Robotics RL800 Robomower available in Amazon's Tools & Hardware (minus a few mower parts). That's pretty good considering the BS2 chip isn't included. The prices for this chip are pretty standard at the Amazon Scientific Supplies, Mondo-tronics Robot Store - 2002, and you'll notice a big choice of BS2 IC's to complete your package.
