Negative Positive
Title: Almost works, but disappoints
Review: This engine will actually run for a few seconds, but the cheap plastic gears are somewhat deformed, causing it to constantly stop and bind. Pulleys are made of rubber, and flashing on the them and the plastic also make it stop. A great idea, but stinks in quality. You can get the same exact product at musclewires.com for $49.95 and be 30% less disappointed. It's worth about $10.00 for the removable nitinol spring, but the rest of it is plastic junk.
