One Big Ball Bearing
Stilllearning2•August 30, 2017
This is a monster size ball bearing. I verified with calipers to be exactly 4 inches. Weighs in at about 9.5 pounds. Thought of getting a 5 inch but 17 pounds plus is over kill. I keep it cleaned up when handling it and stored in original packing. Still shiny as new more then 5 months later.
Exactly as ordered, and interesting.

This thing is super heavy -- physically and philosophically. Super shiny, very cool
Unbiased 4" steel ball review
Jairus R.•May 21, 2017
Just took it out of the box. This thing is sweet! Has a mirror finish. The weight of it alone will bring a smile to anyone who beholds it. Pictures don't do justice for the tangible quality of this orb. I used a lathe to build a custom stand blah blah not gonna bore you. Overall, this will make a great desk piece. 5 stars
High quality

Very high quality. Meets very stringent tolerances.
Awesome Steelie for a Desktop!
John Urbach•January 18, 2017
My steelie arrived in a small box, without defects nor blemishes. I say that because I had seen complaint on other reviews. I saw several smaller ones online but wanted a desktop focal point that people would be wowed by. I am going to cut a 4 in block of wood and chisel a little indentation in the top and then put a 3 mm coat of that epoxy like coating to make a beautiful show piece. I love the reflection in it and the mirror finish. It is a heavy ten pounds.
