Exante shakes & soups

Options
Anyone know if these are good? I've seen some on ebay cheap. Thing is I'll have no food in for about a week as I'll have no fridge/freezer (buying new one) then have to restock it by home delivery as I'm housebound. I might get lucky and get a delivery slot the next day but I thought I'd use that week to get shakes & soups diet that I only need to add water (or long life milk that could store in cupboard).

So wondered if anyone had had any success with them and what they tasted like?
