First use of a brass E-collet. Fit and finish - 4/5 stars. The edges are not as nice as in the picture. The unfinished staff was still visible on the large edge. It morphs nicely into the train. I noticed a few chips in the material. Fortunately not in the areas of activity. One of the pins was a bit loose compared to the others; I didn't have a runout requirement, but I suspect it could cause runout issues with uneven tensioning. Overall, it did its job at a reasonable price - for emergencies. I was glad it was available for Premiere and did the job. I'll probably get another one as a spare.
