The quality of this product is great! It's very durable and sturdy. I think we will have it for a long time. One downfall is that the instructions are quit confusing. This is why I rated this with 4 out of 5 stars.  We figured it out obviously but just kind of had to wing it and that was a bit frustrating. I'm still overall impressed with this gearbox.
