These ratchets are very smooth and work well. So far they appear to be of good build quality. However, upon use, I found that the swivel head moved too easily for my liking, making it difficult to hold the bushings securely on the bolt head. I really wish they had a pan head position lock. If they did they would get 5 stars. If the hinge was stiffer they would definitely get a higher score. This may not be entirely fair (3 stars instead of 4) as it is clear that the pan heads do not have a position lock.
