Hi Dolphinscales,
I used to work at Heinz here in Wagga and we used the petrifilm swabs daily as part of our hygiene check. The trick with them is to use sterilised water to dampen them and the rest is easy. They have a large grid on them to count colonies. Overall less fuss to use them, but the cost of them tends to make agar dishes more viable.
Hope this helps,
Lou.

Thanks Lou for that
and thanks to you pommy also- i have the manual and the info. What i wanted to know if they were as good as they say (form people who have had experience with them)- some times it looks wonderful but does not always turn out that way.
