Thermometer

I lik the light for a small nano or pico tank, it looks well made and attaractive. You must press OK to lock in settings though. I used the escape button after setting the minutes to adjust the time and noticed the clock ran an hour behind. Solution: press ok after each setting. It cannot do a sunset unless you program channel three to remain on all night, as leave channel 3, B setting on 1 percent, in which case there will be amoon;ight on all night. Since I am using it on a fluval 5 gallon, in a bedroom, I can't do this, the light is a bit annoying to be left on al night. So 4 stars, if ther was a 4th channel, I would give it 5 stars. Thanks.
