"Ordered an atonic clock movement to repair a very nice poolside clock that stopped working. Prompt shipping and easy replacement. With it's radio synchronizing signal and it's Quartz movement, it was suppose to be 'crazy accurate'. New movement worked for about one week and then displayed all BUT the correct time. Did all of the things to correct it, new battery, reset button, another new battery, etc. Called Klockit, they assured me this was a one-in-a-thousand BAD movements. Sent me a replacement. It work 5 days and did the same thing. I even took movement out of clock and taped it to a wall far, far from anything that might interfere with radio signal. With new battery in place, it too worked about a week."
