They brought it to us as a gift and my little one loves slime. It didn't disappoint us even though it came defective, the chimney was missing - I sent a message to the company but never received a response, not even a "sorry, there is no replacement available". So the experience started off a bit negatively. UPDATE: The company responded after 2 months and sent us the missing chimney without any charge, so kudos to them for this gesture!
The powders are the typical ones, nothing special. If they run out, you can buy slime powder to continue making it. Approximately 60g costs €1 at toy stores with slime.
The feeding etc. is fake, it only produces tears.
The mixer does indeed mix and with the spatula it becomes slime.
The glitter is a bit dangerous, don't give it to the child without supervision if they don't know the golden rule "Never glitter near the eyes".
Other than that, it's okay, it requires imagination for the child to play with it for more than a few minutes. It's quite expensive for its price, so only buy it if the child loves slime and will play with it.

In my opinion, it is definitely not worth the money (I bought it on 06/12 for about €38). It has some ingredients in small bags in order to prepare the recipes using the game's components to feed the plastic doll that is included. However, these ingredients, when you prepare these recipes and put them in the 4 small jars that are also included, I haven't understood what else you can do, since the main axis of the game is the preparation of the ingredients into recipes, the instructions of which are included. (If anyone knows, please inform me, because spare ingredients, in a first search, I haven't found).. I mean, I think that in a few days the child will get bored of this game. Also, it is not stored particularly easily.. so and so
