I submitted the below review out of frustration at not receiving a response. I eventually did speak with a CS rep. and learned that the photo on their website was very dated, and never actually depicted the seat they sell. They offered me a full refund. I did not receive the "Zippy Seat" that you represented on your website. The seat I received does not have an important safety feature, a raised back. I have sent two emails to you indicating this, and requesting an immediate replacement, but have not received any response. I purchased your zipline last year and was pleased with both the product and the support I received. However, I am now wondering if my initial impression was wrong.
