This has smooth ball bearings and moves freely. The wood is smooth as glass and does not snag the fiber. I have thought about this type product for awhile but they tend to be pricey. This is extremely reasonable and an exceptional value. I should probably get a 2nd one for color work.
I've used several different styles of yarn holders and these are the best I've ever had. Rotation is smooth without drag and holder is sturdy. Quality product.
