Grazer disc

[iLMaRiO]

Anyone using the grazer discs like the ones from Vitalis or similar ?
I've tried multiple times but every time, after a couple of minutes, the disc breaks and goes to the sand. It's impossibile to keep it attached to the sucker

Any idea?

I've tried the 12mm NLS wafers and the fish seem to really like those.

The ones from vitalis are absolute rubbish. As you say, they break apart and end up on up in the sand. Mine don't last longer than 5 minutes. I threw the stuff away...
