I have Scotkat, just one bag, but only for topping up the big pots with roses in them after scooping off some top soil. The jury is still out. It is expensive for a small bag and not easy to judge what you need to put in to get the desired level. So probably not to be a repeated purchase

This is what I have been hearing Dorjac

Many thanks

I think the price is ridiculous over £9 a bag here.
