I received my items very quickly. I also appreciate that I received 30 units instead of the 20 that I ordered. However, I should have looked closer at the large group photo that was sent before shipping. Out of the 30 units that I received only about 4 were usable. These are very small parts that require tight tolerances to be usable. I have had other manufacturers from Treatstock send 100 units that were almost all identical. I have included a picture of pieces lined up to show the variations. The one on the left side is probably the only one that seems to be completely correct out of all 30.
