To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Great toy - only thing is I think it is suited better for 1 child. I got it for a little girl who has a sister roughly the same age (both around 7) and within a few hours they had used up almost all of the string to make lots of bracelets. Maybe I should have got a bigger set because I chose this present to encourage them to share anyway... but either way they liked the little changing disk things they thought they were cool and it did keep them occupied with little help from their mum. They just needed a little help measuring the necklace to size as they didn't think to make it longer so they could slip it over their head.
We made three little necklaces, two rings and 3 bracelets with this set and have some beads to spare. The rings needed a bit of glue (not included) because the sticky pads aren't really sticky but luckily we had some lying around. My 4 year old loved it.
