My counsellor JUST had them is stock brand new out, they are neat have a wee pouch and fit in your pocket or handbag. They would be good when your our or at work. They dont look incredibly substancial but she had said they have had a very good feed back. BUT......they are £7 odd i havent invested just yet because of the price.
I find the soups dissolve well enough in hot water, and was normally home when I had the shakes. I have got one of those cappucino whisk things that someone on here told me not to buy but I thought did I good enough job on the shakes. It only cost me £3.
