The Thebes TIMER 26 is now not exactly what you'd call expensive, but it is more expensive than the Chinakram. For this he makes reliable exactly what he should: switch the lighting of an aquarium. No manual? So please ... Who needs a manual to the correct time to adjust and be able to serve the small plastic parts in accordance with the times to be switched? Just. :)
For me very convenient: With the small rotary switch on the corner, the light can sometimes turn quickly if you want to clean the pool for example still and it is actually already "sleep" in the aquarium. No tedious turn off and plugging the plug but simply on the wheel and it's light.
I have the time clock for several weeks now in operation. Absolutely reliable, easily and at no extra batteries.
Who, of course, individual programs required (different times or on different days of the week), will not be happy with the device. (Control aquarium lighting) For the purpose that I use -> properly. Strong buy recommendation!
