It does what it says on the tin.

Providing you can read this in the dark (a red torch may be handy) then this does what it should. I don't see how I can give it a higher rating, though there isn't anything wrong with it.
There are others out there that give you more information, and I have seen some that glow a little in the dark (or under torch light) so they may be easier to use.
But for the price, you can't go wrong.
