The most over-marketed product around at the moment. This stuff is being heavily pushed on children's TV, and sadly my six-year-old persuaded his grandmother to buy this set for his birthday.
(i) the sand comes in little polythene bags - no other way of storing it, so when you've played with it once, good luck to you.
(ii) the sand (of course) just mixes together and looks pretty ugly once it has. This is bound to happen after the first time you've played with it.
(iii) you have to use considerable force to push the sand into the molds before trying to get the shape out. 80% of the time the shapes will collapse when you try to get them out - even more often if you're under 10. Disappointing. This doesn't happen with other modelling toys.
(iv) the picture is _so_ misleading. Frankly, unless they just happen to be artistic prodigies, there is no way that the kids in the advert made those shapes.
(v) this stuff is _so_ expensive! Please please buy lego - paints - playdough - books - ANYTHING else. It will be better value for money.
