We use Terra teeth on our  Komatsu and Cat Excavator fleet. We found Terra Teeth to have much longer wear life  250 hours using ESCO vs. 600 hours using Terra. We found teeth to retain shape and sharpness into 550-600 hours.  We would highly recommend anyone in the industry running GET to run Terra Teeth without hesitation. -- Darryl Warren, Warren Brothers Earthmoving Pty Ltd
