Hi Scot,
I've been using it for a few weeks (At least the sweetcorn version), it definitely works!
I've had some nice Rudd on it, it's extremely useful for keeping a bait out there long enough for a decent specimen to find it, despite the attentions of smaller fish.
I haven't used the H. pellet version yet but I'm going to give it a try in France next week. According to Dave Chilton from Kryston, they're adding some other versions, including Luncheon meat, soon.
Regards Chris
