I bought two of these for my Tascam 38, they are new, unused, firm and lock the reels tightly, there is no wobbling even at the maximum rewind speed.
The Tascam 38 winds back at extremely high speed, any movement or wobbling would be damaging for the machine itself. So I am very satisfied with this product and also the price that is correct.
I would recommend this product, it's a premium quality NAB, not a 3D printed (copy), or so called "Old New" that are used and that can be found on a certain popular online website.
