A co-worker of mine had one of these on his desk at work and from the first time I tried it I wanted one. I tried to buy his but, he wouldn't sell, so I did some research and found this one on Amazon. I actually got it for 12.00 cheaper than I offered my co-worker. It shipped and arrived very quickly with Amazon Prime. It's been sitting on my desk at work and unless I'm typing I'm spinning it constantly. This thing spins on a bearing and it seems like it can spin forever. It's a lot of fun and keeps me entertained while reading or just pondering. I'm glad I found this guy or I'd still be bugging my co-worker. It's very well made, brushed aluminum with laser etching and like I said earlier- the bearing makes it spin for a very long time. If anything ever happens to this one I'll definitely buy again.
