The first thing I liked when my set arrived was the sturdy case, well made and durable. Open the box and each piece is in place, labeled and easy to find. Every detail is well made and finished. I found the right size for the hub I was working on, it fit perfectly. Best of all is the main bolt which is hardened, strong and well made of metal. Easy to replace wheel bearings. This set is of excellent quality and well worth the money. Orion kicked him out of the park because of it
