Can't beat for the price - it is just as described. I've had it for about a week now, its accuracy is still within a minute of the actual time. Its a bit larger than I expected, for some reason - the digit plates are about 2.5" square (the ones I remember from the '70s were smaller), and the whole clock stands about 6.5" tall. I was hoping to find an AC powered version, but this one was the only one I can find - it runs fine on the single D-cell batter, which goes into the cylinder in the center of the clock. I also bought an AC adapter that will do 1.5V and plan to wire in a socket so I can power it from AC. There is a small bit of motor noise (you can hear it running in a totally quiet room, for example), and the expected "click" once a minute as the number plates advance. Take note of the expected delivery date - its shipped directly from China and perhaps not manufactured until it is ordered. The estimated delivery date for mine was a month away, yet, in my case, it was actually delivered within two weeks, although other reviewers noted almost the full four week delay, evidently. I wasn't in a hurry, especially as it was around $30 cheaper than other similar units.
Update a month later: still running great, time accuracy still within a minute (if not exactly correct).
