I had an issue with my second electric cultivator/tiller, model TJ600E. Last year, my first tiller was replaced under warranty after one use. This summer, the replacement tiller stopped working after one use. I'll be interested to see how next year goes with the third tiller. It is hard not to be skeptical about the reliability of this product. However, in each case, customer service was prompt and responsive to my needs and quickly issued instructions and free return shipping label to receive a replacement tiller. The company certainly stands behind its warranty.
