Returned the watch. The main problem was that it did not maintain correct time -- ran too slowly. Also, it was a pain to make any of the settings, so the prospect of having to reset the correct time multiple times each week was not acceptable. All 8 alarms did work, including vibration, though. The customer support rep was very friendly; said there was no way to adjust the watch to speed it up or slow it down -- we could try replacing the battery, but she explained that the process for doing that was a bit involved, due to the sensitive placement of the wires within the case that were associated with the vibrating alarms -- said they would be happy to talk us through the process over the phone if we wished -- or we could mail it to them and for $18 they would do it -- but in any approach, a new battery might not correct the timekeeping. Too much trouble, and no guarantee it would work, and if it did work, how long it would last.
