Klout Question

[music_man_66]

I have three Klouts that I recently acquired. I've checked their serial numbers to place them in their production lifespan.

Can anyone tell me what serial numbers were on the go in the final year of the Klout's production?

Many thanks.

I would be interested to know this too as I have a klout with a very high 5 or 6 digit serial number that I have been looking to find a partner for but never seem to find anything even close. I can’t remember the number of the top of my head but remember the original box is brown yet most of the ones I have seen come in white boxes.
would be interesting to know why the serial numbers jumped from 4 digits to 5/6 long.
