Rennies extra are very good and do what they say on the packet. I thought I was getting them cheaper than in the high street but it works £1.70 dearer than on the high street I must admit when I ordered them I thought I was buying a pack of 24 and have never the 12 packs in the shops if it had been the 24 pack it would have been considerably cheaper never mind
