I ordered a grass/brush trimmer blade attachment set for my electric trimmer. It arrived without the mounting adapter which is needed to attach it to the trimmer. Without the adapter it is useless. The ad said the product came with everything needed to easily attach it to any model of trimmer. Rabbit Quick made no attempt to correct the error and after several months of back-and-forth advised me that I would have to send it back to them at my expense, at which point they would decide if I was going to get a refund. The shipping cost is higher than what I paid for this useless item. The company is very unresponsive and unprofessional. Don't let yourself get scammed!
