I bought this as a replacement for the Salter 1600 which uses the same accurate strain-gauge measuring engine.
The Salter 3003 wins hands down over the 1600, because it uses proper push buttons, and weighs ingredients up to 5kg not a mere 3kg.
While not quite instant, the 3003 has a good and well-damped response, you don't have to hang about waiting for the reading to stabilise while adding ingredients.
It is not cluttered up with silly menu systems or redundant features found on some others we looked at.
It is simple and intuitive to use, quick and accurate. What more do you need from a kitchen scale?
Postscript. The pair of batteries lasted for about fifteen months of daily use before the readings became erratic. But then the replacements CR2032 Battery (2 pack) - Panasonic, Lithium Coin Cell, 3V
were very cheap.

I've just put a second pair of new Panasonic batteries in. After almost three years, the Panasonic ones that came out have lasted much better than the set that came with the machine.
Addendum 23rd October 2013.
I've just put a third pair of new Panasonic batteries in after only fifteen months again. But we have been using the scales a lot recently and the new cells
are amazingly cheap.
Addendum 11th February 2014.
It was dropped into a sink full of washing-up just before Christmas, and, as one might expect, it stopped working. I removed the batteries, carefully took all the covers off and rinsed it out with clean water. Then it was allowed to dry in the airing cupboard for a couple of days. After reassembly it worked again, with the same batteries. Result!
