At first I thought it was a device that you take with you to the store - I thought that after reading above and first visiting the KS page. But I'm pleasantly surprised that it lives in your kitchen instead. Simple. Brilliant. Useful.

This is most definitely something that could technically be done with a phone, but it would be clumsy and wouldn't help anyone else in the household.

I think if it had received more blog publicity it would have been backed a long time ago. I'm sending a tip to a few places now.
