We hung this clock in our math tutoring center, and it's perfect! I love that the second hand scrolls quietly instead of ticking. It's been up for a few weeks now and keeps good time.

Fun clock and works as it should. Keeps perfect time.

This arrived broken. It was boughy for xmas and we didny even get to hang it up bc the hands were too bent which made them flop downward. I DONOT recommend this item.....very disappointed.

I like the use of only the number 9 for marking the face of the clock. The clock is flimsy plastic. I saw it elsewhere for $49.99 and am glad I did not pay that much for it. The seconds hand is swept rather than pulsed, so I suspect battery life will be shorter than pulsed. On the plus side, it is silent instead of ticking. The AA battery fit poorly into the compartment. I prefer clocks that synchronize to the NIST atomic referenced radio clock, so the accuracy won't be up to my liking but I knew that from the outset. A good novelty item for under $30.00

I bought this for my daughter who works and teaches at a University. I bought this for her office and she just loved it. She was the only one that could understand all the mathematical formula's. Recommended for those who love and breath math.

I am always staring at it and explaining the solutions to the equations to folks that do not understand them.

Fifth grade granddaughter loves it.

As a math teacher, I've been wanting a clock like this for a while to hang in my classroom. Unfortunately, it wasn't what I expected. This is a flat disk with a clock mechanism attached. It will not hang flat, so it is at a perpetual angle and easily knocked off, which is exactly what happened as I was attempting to get it to hang straight. Needless to say, it split right down the middle. Since it still kept time I taped it back together. Do yourself a favor and find a different clock. The ten dollar clock at Mardel's at least hangs flat .
