Nematode experiences?

Has anybody used these this year? my main problem this year has been with slugs. Traps, organic pellets etc etc, and they still manage to eat what im meant to be! Totally eradicating a problem is neigh on impossible i know but i have read some interesting advertisements, claiming that they are really effective. The experiences of fellow gardeners is more trusted that ad campaigns though!

I have used nemaslug for the first time...it hasn't completely stopped them eating but has slowed them down considerably...I'll use it earlier next year...that combined with plastic tubs of milk seem to be saving a lot of crops
