It was a decent tool for the price and did what I needed. However, it was very difficult and troublesome to hook the hooks on the spring as much as possible. Also, I had to use pliers to clamp the part of the tool that was pressing on the top of the spring because it was too far apart and couldn't sit evenly on the spring. It takes a little courage and patience to attach it to the feathers. Also, it was quite bulky, so it was very difficult for me to properly install it in the right places.
