Good timer

Wish it had a 3 Sec beep before start of each EMOM round and not just the first round.

Stretch 1954 ,

All I wanted was a simple to use timer.

With this timer I can set a "set-up" time to get myself into stretch position as well as the 30 seconds for the stretch itself. Terrific and simple to use ! I hit the start and it gives me 15 seconds to get into position with a 3 beep countdown just before the stretch 30 seconds starts.
