  • Blackwall 330 litre Compost Converter 4/21/2020
    Ordered this on 24/03/20 as my local council has cancelled garden waste collection. Website warned delivery could be up to 28 days ivo current situation, but the composter was delivered 10 days later so I was very pleased and also very impressed at such quick delivery in these challenging times. The composter seems solid and strong and I am one very satisfied customer. Will definitely use this company again.
