Probably won't be much to review, apart from maybe more details of the shop extra channel, be just Simon wasting more vegetables and milk, selling products that have been available else wheres for ages, just because he found a Chinese supplier to stick the Piranha branding on the products doesn't make them any more special to the hundreds of alternatives out there.
The Piranha products are hard Company to track down, they've a web site and address but no company details seem to exist at Companies House, although Simon Iles claims to be a Director. Wonder if they are just a brand he's create for his "Seen on TV" company.
