Review on Enhance Your iRobot Experience with the iRobot Left Wheel Module by Yekaterina Brown

Expensive, but worth it! It arrived quickly, with installation instructions and an email address to contact for help. No need to write other than to say I appreciate the good customer service. My robot works great! Also, I'm 84 years old and I'm a woman! All done, disassembled and reassembled without outside help!
