Excellent value for the price. Very nice machined finish and the threads for the nut are very smooth. My My ER40 Teckniks collet snapped right in. Recommended!

Okay China, I see how it is. I haven’t checked runout yet but my initial impression is WOW. I think I have to report for false advertising because the unit I received is better than the one pictured. All the holes are debured, especially on the back side which is critical. It arrived cleaner than the one shown and very appropriately oiled, not too much 👍 The threads are very smooth. Upon closer inspection I see wear marks on the internal taper. This is a good sign as it indicates they are actually testing every single one sent out. Value for money is probably the best I could imagine on Amazon if the runout is good. I’ll update my review when I get around to it.
