Review: Very fun product - This arrived well package from the seller and a new condition as expected My kids loved doing this if is fun and exciting, but it is not like the soft gummies that you buy in the store it has a firmer texture and a different flavor but that is part of the fun because you can use the different ingredients to make it turn out differently and have it as a learning experience. I would recommend this product but just let your kids know that it's going to turn out differently depending on how much of each ingredient you add so they know to expect it to not taste like the packaged gummy candy!
Review: Fun and delicious - My grandson loved them. He’s eight and what eight year old doesn’t like bug gummy’s? These were fun and easy to make. He loved the taste.

### ⭐⭐⭐⭐ Better for Older kids and lower your expectations.
*by S***N on September 11, 2025*

Great idea, but is a bit difficult to work with. Consistency is poor, we had to keep adding water and reheating. Great idea, but need work on quantity.
