We stocked up from you at Cardiff RHS last year but with no show this year I am buying online. Your big 400ml Simply Green Diffuser is incredible, we have an open plan kitchen leading into our conservatory but the reduction in flies last summer was unbelievable. The fragrance is so fresh and everyone last year commented on the amazing smell in the kitchen. Has lasted just under year and the fact that it is totally natural is amazing. A very clever product.
