Hello Anita2003.
Thank you for sharing your feedback. We understand that comfort and ease of use are important, especially when transitioning from a string trimmer to a dedicated edger. For handling and control, we recommend ensuring the auxiliary handle is adjusted to a comfortable position and that the shaft length is set so the blade rests flat against the edge with minimal lifting, which can help reduce strain. Taking shorter, slower passes can also improve control while getting familiar with the tool. Regarding returns, returns can be initiated in accordance with our return policy. Full details are available here: https://www.greenworkstools.com/pages/return-policy. A few key points to keep in mind: returns must be initiated within 30 calendar days of receiving your order, customers are responsible for return shipping costs, and products must be new, unused, and in their original packaging. We strive to provide a return process that is transparent and consistent, and we continue to review our policies to improve the overall customer experience. Our success team is always available to help review available options and ensure the product is operating as intended. They can be reached either using the online chat function on the Greenworks Tools page or by calling 1-888-909-6757.
