Banggood.com kindly sent me these items for appraisal and review. Eventually got to testing and this video covers the findings. We found a run-out problem which seems due to the collet holder have its locking nut not running true, which leads to a collet being itself out of truth. Could be the threads at fault. This is probably a one-of faulty item and we hope to get a replacement eventually to permit fresh tests. Overall finish is otherwise very good.
