Favorite light timer

I have a "grow" brand dual outlet manual light timer. Not sure of its reliability bc today it didn't turn on as expected but I may have been a few minutes early. Looking for something a bit more reliable possibly but wanted to ask the forums if I do indeed need one. Here is the one I haone of which everything is physically the same except the brand name:

These are what I use and love, and they have a battery backup to retain settings.

I have 2 of them I've been using for about 8 or 9 years now and just bought another.

@Kerovan I use those exact same timers for my lights.

I use an Idevice switch.

I use the Apollo 18 dual outlet digital timer, you can program 2 separate timer schedules, I'm running 3 of them actually.

Good thread. I use this one, because I'm a cheap skate. Its the same old design I've been using for decades.
