I recommend it's really nice, comes with the small key BTR if ever the wheels loosen. Comes with a white LED and another multi-color led. The system only turns in one direction so well checked the polarity before soldering the led.

It was a very pleasant shopping experience the product is of excellent quality and meets the said. I appreciate the fast shipment to Colombia.

Beautiful. Really cool, well done! Great ornament and functional! Is not perfect mechanically but far beyond expectations! Recommend.

came well packaged. works like a charm. great for science demos in class. instructions in english are minimal, could be better.

Thank you cool thing, my husband liked the gift. We haven't started yet, we need alcohol. But I think it will be fine.
