          Not completely satisfied
          I recently decided to replace my 20 year old pool timer with this new replacement model. The specifications for each were exactly the same, namely T104. I liked the fact that this replacement unit came in a metal casing rather than a plastic one. However, I have mixed feelings about this timer. First of all, there were no instructions included other than a wiring schematic. I would have appreciated a written description of the features. The available YouTube videos did not answer my questions. For example, what exactly does the ON/OFF switch do? I finally figured out that OFF does not turn anything off, it just makes the circuits respond to the timer. So how do you shut off power totally if you need to? No answer there, other than going into the garage to the main fuse box... Also, the unit has a flimsy plastic sheet to protect the user from receiving a 240 volt shock. Could the manufacturer have come up with something safer? When feeding in the lines, one of the steel holes was too small, necessitating quite a bit off sanding with a file. Finally, I had trouble closing the box when everything was connected due to the fastener not being properly bent. All in all, an electronic timer might be more practical than a mechanical one.

                Timer Replacement
                My pool pump clock quit after 20 years of service, so I bought the T100 from Home Depot expecting to replace the whole box but happily found the internal mechanism simply fit perfectly into my old box and I was back in business within 15 minutes. It seemed too good to be true. Couldn't be happier.
