I bought this set, used for a few days, then bought the Avent VIA set (which is around 11 pounds). So I can compare the two sets:
Happy Mummy: 8 containers, flimsy, cheap looking, 70ml container, got stained after I put carrot and pumpkin puree in there. Bottom line: not worth buying
Avent: more expensive, 20 containers, 2 different and bigger sizes, much higher quality plastic, has measuring on the container, comes with a recipe booklet and 2 great spoons. Bottom line: value for money.
I wish I had bought the Avent set first, then I don't have to bother buying the Happy Mummy set.
