I got this for my kids so they could have something fun and educational. I've done other STEM kits with them like "underwater volcano" that are fun but have no lasting value - you can't really repeat it without buying refills and when it's done there's nothing to show for it.
The crystals are interesting because you make them and then...you've got some crystals you can hold or look at, and they're pretty colors on top of the lighted stand. It's hard for small kids to help because you have to boil the heck out of the solution and the instructions make it very clear that the powder is toxic (don't inhale it) and the solution is toxic (don't touch it, don't drink it) until it dries. They can at least watch you do it and you can talk about what's going on, and they can help put in the starter if they're careful.
My favorite part was the couple of weeks the crystals were growing. Every day my kids would want to look at them and see if it was bigger. Eventually the crystals are done, you pour off the liquid, and you can see them while they're drying. Then you pull them out and put them on the stand. My kids really enjoyed holding the crystals to see what they feel like and looking at the colors and how you can see through them. All three crystals on the stand actually makes a nice decoration for a shelf and you can say you made it yourself.
Not a lot of downsides - you can only do it once but you can space it out by making the crystals one at a time and you do at least have pretty crystals at the end. The crystals are not sharp but they are pretty fragile so you can let kids handle them but it's likely some of the ends will break off sooner or later and I imagine you could crack or shatter one if you dropped it on a hard floor. The lighted stand has a capacitive touch power button and ours is sometimes possessed. If you leave it plugged in it will sometimes turn itself on or switch from solid to blinking mode, which is minor but not great.
Overall this is a fun STEM activity where you make something cool and the older your kids are, the more involved they can be in the process and the better they'll understand what's going on, but even small kids will enjoy making pretty crystals at home.

Looking for a crystal kit? THIS IS THE ONE. Fun for ALL ages.
I originally bought and sent this to my 6-year-old nephew, for an activity for him and I to do together when I went to visit him.We followed the directions exactly as in manual. Also, I had read elsewhere to make sure NOT to boil water in a metal pot or it will react with mixture-so avoided that-which the manual DOES NOT STATE. After that, you pretty much dump each crystal powder in the boiling water and stir for 10 minutes. Let it sit to cool, then put in the seed rock. I agree with someone else’s review that a pair of rubber tongs would have been easier to place the seed rock than those included. But I was able to gently slide it into place in center. And that is it!What I loved about this kit and WHY I choose it after viewing MANY others, was it’s inclusion of 3 growing cups (so all crystals could be grown at same time), and that yield time was 5-7 days as opposed to 7-14 of other kits.Within the first day we already had crystals forming. Every day after, BOTH MY NEPHEWS, even the 3-year old were super excited to wake up each day and run to the china cabinet (where we decided these were safest behind glass doors with cats in house) and check the growth progress. I must admit, I was pretty excited as well!We left our crystals to grow for 7 days. I think they could have grown longer but my nephew really wanted them out! He loves them SO much he has his stand in his window so he can ALWAYS see it from his bed and loves how the crystals reflect the light. The only negative thing I can say is the colored crystals are much lighter than they are pictured.This kit was SUCH A HIT, he specifically REQUESTED I get ANOTHER crystal kit to do more when I visit again!

This growing kit worked perfectly! We made sure to follow the instructions TO A 'T' and it produced textbook crystals! I purchased it for my daughter (8yrsld) for Christmas and she loves it! Super fun project to do with the kids, and since there are 3 crystals you get to spread the fun out over several weeks. It also allows you do see how well one grew so that if it didnt turn out right you knew to be more careful with it next time, or if it did turn out right (like they did in our case) to be sure to do it the same way the next two times. The instructions were very easy to read and even had little tidbits about crystals between steps, which was an added little treat that my daughter enjoyed. Simple put, I cannot recommend this kit enough! Just get it! You and your kids will love it! #sciencerulesReviewed in the United States on February 13, 2020

Some helpful hints:
- dont let the crystals grow past the top of the fluid, the tips get a little "crusty"
- add a bit more water than called for, but not much (partly to prevent the above)
- give it PLENTY of time to dry out. Like 1-2 days after you pour out the water. Luckily my kids were very patient (shockingly)
Amazing educational gift for both very young and not-soyoung kids!!

Amazingly good kit! My 8 year old daughter and 3 year old son both loved making it and seeing the results! We followed the directions exactly and it worked out beautifully. Pictures has both flash and no flash so you can see the effect of the base. And the light up base is an excellent touch.Reviewed in the United States on May 20, 2020
