Is there any difference between the perfect prep and the day/night one?

[brokenhead]

I can see that the newer one is more quiet (or reviews say it is) and it has a little light? Is that the only difference?

Has anyone used both and what would you recommend? I had the original perfect prep, well actually we had two one upstairs and one downstairs. Does it make a difference and should I get the newer one which is double the price or two of the normal one?

Thanks

You know they just measure the powder right? Save yourself the cash x

They measure the water not the powder, or does the new one also measure the powder?

It's to do with having a bottle ready to drink at the right temp you can't do that with a kettle .. so it's much much quicker
