Good finish, very smooth. I like the flat sides. The diameter is very even. However, there are big differences in coil length. Look at the picture that shows the rings around the edge - you can clearly see the difference in the gaps between the ends. Fortunately, this doesn't affect my intended use, but may be a hindrance for others where consistency is a high priority. Spring tension is very good. I opened the end of the ring almost 1/4 inch and it rebounded firmly without stretching or deforming the coil. Overall this is good value for money, less than half the cost of some similar products.
