Cycling computer with the quality of a sigma-product

That reminds me of the last cycling computer has been stolen when I was a little careless, now had a new coming. As a die-hard fan Sigma came for me no other device in question as a Sigma.
The requirements are rather plain with me, easy to use, robust, reliable, easy to read and good for purse.
Not long sought and the Sigma BC 12:12 found. The cycling computer has all the necessary features that you would need for cycling.
However, there are functions not open up their meaning one necessarily immediately.
The Spritverbrauchtsberechnung is probably as a function of the predicate funny.
It provides a fuel consumption, eg 8 liters per 100km and can then read how much fuel you have saved when exiting a tour. A function but you can definitely do not need. Seems 12:12 to be present at other bike computers I have not seen it even in the Sigma BC.
One can argue about the built-in thermometer, I think it's good.
Conclusion: Anyone looking for a solid cycling computer, should get this one.
