All pictures on instagram make this product seem far larger than it is.
I bought this for my brother as a birthday gift. He absolutely loves it! Such a cool product and happy with my purchase. The only thing that wasn't great was that the light does not come attached to the container and it died after a couple days but no big deal. We got a replacement light and its all good now. I would recommend this product for anyone.
I really like the clever design of this product. the screw thread makes for a fascinating parade of ferrofluid spikes. I feel kind of picky when I point out that the glass bottle is optically quite poor. It looks like an ordinary food quality container. I would be much happier with the little gadget if it cost 50$ more and had a higher quality container.
The way the ferrofluid moves is amazing! Very mesmerizing.
Gave this as a gift, been told it's incredible.
