Saves your electricity and your batteries...
If you are on your phone all day, like me, you'll often find it difficult to give the phone the 2hr charging time it requires other than at night... But if you keep it on all night the battery of sure to swell or loose cycles... This gadget is the perfect solution for this... Though ots a lil complicated to learn and use, once you begin to use it, it works like a charm... Unhappy about the packaging and the lack of user instructions... But very happy about the product... The price is also very steep as I found the same product at half the price when I began to look for tutorials to operate it on google...

read how to use it.
works good. but the instruction manual was very poor..actually useless. i found a video on internet on how to use it. it comes with german type 2 pin plug so wont do the earthing for 3 pin plugs in india. for ease.of use..see foto of the keys or pins that the manual refers to. u need tp press it down where u want ON state. last foto shows it betyer from side. u can use ur nails. each pin is 15 minutes. oh and u have to slide the switch to clock. also see the arrow in second foto where u have to match the clocktime. her3 it is at 1 pm. the dial with 24 numbrs is clock. dark is night. timer works only when plugged in.

Good enough but has some caveats
A good enough product that works fine. However, it slows down a bit everyday (by about a minute or so). Moreover, the timer stops when there is an electricity outage. It will lag by the same amount as the electricity outage time period. So, the time has to be set again in order to use the switching function at the correct time.

Usage as timer
A great product. Perfect mechanical timer mechanism. As long as the electricity does not go off, the time is maintained perfectly. I've been using this during Diwali and Christmas for lighting and don't have to worry about switching the decorative lights installed outside the house, off, at night. Simple, easy to install and instructions provided.

Why can't you provide a battery backup during power failure
Everything is fine but during power failure the timer doesn't work and works when power is retained and this breaks the time defference. I want a timer which works during power failure too. It should be provided by a battery backup to keep time current time
