I've become obsessed with tops since I started working from home. I only get the inexpensive ones so far, but this is one of the best! When it says 5-8 minutes spin times, believe it! On my first spin, I started it, was doing something else for a few minutes then started watching a video. It was 6 minutes into the video before it stopped! Nice machining and balance! (Spun on a 4" spinning glass. Size does matter.)
