I would not put DS 2500 on a shopping trolley myself.
Greenstuff(V4) formula is crap, but redstuff is ace, WAY better than DS range, or Mintex/pagid.
Yellowstuff is also road approved and works from cold.
I have tried all the above and now use redstuff but trying yelowstuff next.
NB pad cracking down the centre is NOT a fault, and pads are pefectly ok, though it worried myself until I had it confirmed by three diferent pad makers.
