It's fine until it isn't. For some reason DST just stopped working this year. Changing the setting doesn't change the displayed time at all.I've been a fan of this brand of clock for years, but there's always issues around DST. I think it's clear they will never sort it out and it's time to find something else.

Easy to set up and connected to the atomic clock within minutes. Display is large and easy to read. Outdoor temp sensor seems to be accurate, and the wood finish looks great!

This product works great. - I had a little trouble at first syncing to the NIST Atomic Clock, but it eventually synced up in approx. 12 hours.

This is our fourth Marathon timepiece, and the 2nd with automatic time set. They improved the Time Zone setting to a slide switch on the back instead of going through the options. And, AA batteries are included, so I was able to set this up out of the box.The clock digits are large and are clear from across the room, at all angles. The outdoor temperature is nice to have, as is the Day and Date display.

Me tardé mucho en decidirme en comprar este producto por el precio, lo vi más barato pero al entregármelo venía sin el empaque de mensajería, es decir el repartidor sabía que producto era, aunado a eso la caja original venía sin sello, es decir abierta, los materiales son mejores a lo que esperaba y destacan mucho la fácil lectura por sus números grandes, pero no es así, es de difícil lectura por su fondo oscuro, total deje el mismo reloj grande analógico con fondo blanco y el nuevo lo puse en una mesa, lo de reloj atómico no funciona en Monterrey N. L. Y tengo mis dudas de la veracidad de la temperatura exterior.

The wall clock comes extremely well packaged and was very simple to setup. Insert several batteries and the clock is ready to go. There is really no setup except deciding where to place your clock.The clock is close to perfect if you want an easy to read clock that displays time, date, and temperature inside and out. It's very thin and easily wall mountable or can be placed on a flat surface against a wall. The numbers are large enough to read at great distances. The display is absolutely perfect and can be seen up to 20-30 feet away. It also can be placed on a desk if facing a wall.It seem like an outstanding wall clock and if it lasts and continues to provide accurate time is a superb purchase, Overall, it is well worth the asking price and I'm glad I bought it.

I gave it a 3 star for accuracy, but I used the probe connected to the transmitter, with the probe outside and the transmitter inside the window. The outside temperature reading is 4 to 6 degrees Fahrenheit too high. This could be caused by radiant heat from the inside of the house. I plan to move the transmitter to a better location to see if I can get a more accurate reading, if this works, I give it a five star for accuracy. I really like how easy it is to read and the set up. I had always bought La Crosse atomic clocks before but some part would stop working after a few months. They were inexpensive, but less than satisfactory. I hope the Marathon will last more that a couple of years and that I can start receiving correct outside temperatures. If this happens, the clock is worth the price. I really hope this occurs because I bought two of the units. Also one outside temperature transmitter works for both inside receivers.
