I am amazed: didn't have to manually change even one clock! Cellphone, QC. laptop, & Garmin, all changed automatically.
Way better than the days of going through the house changing everything [incl stove & microwave] and somehow, missing one somewhere, like my watch....
I was excited about gaining the hour until my sister insisted that i come over and change all her clocks, which she collects. So that took me two hours. Net, i lost an hour.
