Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.

Rock solid machine (pun intended)

I have purchased many "hobby" rock polishers over the years (for me and my kids) They usually don't last more than a few cycles. This one seems solid! Easy to set up and use and very quiet... for a rock tumbler. This is the first one that has NOT been banished to the garage. Also, I can get replacement parts if needed. Great machine!!

Nice rubber based roller

It's nice that you can set a timer for each phase. The kit comes with lots of stones, but only one set of grits.

GREAT TUMBLER THAT IS QUIRT AND SIMPLE TO USE!

Easy to star tumbling on day 1. Noise level is much quieter that childs tumbler we previously used. Much larger capacity than other similar models. Great tumbler for beginners!

Love the tumbler, love the customer service more

Purchased this for my sister for her birthday. She absolutely loves it. Unfortunately, the tumbler motor we received was faulty and stopped working at the start of the 4th grit. She emailed customer service and they responded literally in 3 minutes. With in 10 minutes they shipped a replacement out for her. 10/10 recommend!

Great tumbler and makes beautiful rocks!

I wanted to tumble rocks for my retirement project. I have two Natural Geographic tumblers now and have them going nonstop. They do a great job and the rocks turn out beautiful!
