Seems to work well but no instructions on how to set the timer functions. There is a sheet that shows what each button does but doesn't explain it. I've searched the whole internet to see if anyone has any advice but there is nothing anywhere on the internet. If you set the function to "all day", it will only repeat every 12 hours. Obviously you'll need to use it with an external timer to turn it on and off as there's not really a timer feature, including the device. This is contrary to what the ad says. So unless you want to try and figure out what all those buttons do, and I had an external timer anyway, I wouldn't buy this again.
