Sunnytech Solar Magnetic Levitation Model Levitating Mendocino Motor Educational Model ST41

There are a few things that are confusing about this company and product. First, I want to make it clear that this item is manufactured in China. Some of what is put in the ad could lead someone to believe that this was made in the USA but, that is definitely not the case so, if you are sensitive about where it is made, just understand that it is clearly labeled "Made in China" on the box it is packaged in. Also, some reviews have commented that it doesn't come with a manual but, the one I got did...well kind of. It came with one sheet of typed print that gives some suggestions and pointers on how to use it. It is pretty obvious that whomever created this "manual" did not have the benefit of proof reader to check the final version because, it is really difficult to understand their translation of what they were trying to say.All that being said, It got to me VERY quickly, in perfect condition and very carefully packaged and protected. It was even wrapped in aluminum foil, I suspect to function as a Faraday cage to protect the electronics within. That is something I have never seen before but, if that was their intention, I am impressed with the fact that they took that precaution.If you are looking for something that will excite and entertain you with lots of action, you may be disappointed with this device. If, on the other hand, you are looking for something that is well designed and elegantly displays some amazing laws of physics, this will not only please you but, it will also make you happy to share with others and to watch it function.I have not included any videos or pics because there are already plenty of those here. Suffice it to say that it came right our of the box, meticulous wrapping and just started working perfectly!!! It is precisely balanced and regardless of some complaints I have seen posted about having gotten units that were out of balance, this one spins smoothly and with stability at all speeds and in all forms of light. Just FYI, it seems to function best if the light source is coming from the side of the unit, at a 90 degree angle to the solar collector (Armature or, spinning part). Another thing I have discovered that I have not seen mentioned in other reviews. If you place it in such a manner that the light IS coming from one side of the armature, it will rotate towards the light source. If while it is spinning, you carefully turn the unit around 180 degrees from the light source, it will slow and reverse direction to once again rotate towards the light. It will spin fast enough in direct sunlight to be totally a blur. With lesser light sources, like facing a window just before the sun comes up or, just after it goes down or, from an electric light, it will spin consistently but slowly, still fun to watch and be amazed at. If the light source is or gets too dim, it will eventually slow and stop spinning.IF YOU ARE EVEN SLIGHTLY INTERESTED IN SCIENCE, THE LAWS OF PHYSICS THAT CONTROL OUR UNIVERSE OR, IF YOU ARE A TEACHER…THIS DEVICE IS FOR YOU. I would buy it again in a heartbeat and in fact, I plan to order several more of these to send to friends and family as Christmas gifts. This is something just about anyone would love to own and watch.

Pricey at $70 but it is pretty neat to have on your desk spinning on a sunny day

Ok, I got the thing, and it works well !!!!The only problem is that it's bit off balance, so I have to bend the shaft a little bit, but it runs really fast !!!Then, it goes flying off into the furniture...HahahahahahahaNone the less, 5 stars !!!!!!!LOLBut....If we made a giant one of these things, it should be able to drive an alternator as long as there's decent light.Just this little thing has some strength to it.I put a decent amount of pressure on it and it still maintained it's momentum.The point is that there's free energy out there all around us.Between wind and solar... Etc.... we can cut down emissions and need for oil in no time, if the oil lobbyists stopped giving campaign money to the upper crust of our politicians.The minute Ronald Reagan took down the solar panels on the Whitehouse and decided not to use the metric system is why we're in the place we're at.Funny how it seems like things have only gotten worse in the political arena.Deep State Trump is now hitting that ball out of the park for the Lobbyists with more lies.Maybe once winters no longer exists and all the ski slopes close down we'll start to open our eyes.Until then, I hope more companies like this sell these toys to show our youth that there really is hope out there for the future of the world.Sorry, not being political, just naming humans that stopped progress in the world.In hundreds of years from now, Historians will not look kindly on the turn of this century.Honestly it's an embarrassment that it's also recorded on video for them, but sadly it is.Anywho, have a great day and do something nice for another person today !!!The future is wide open, as long as we strive towards that, the rest will follow.-Les:-)

Seems cheaply made for almost $70. It does work well and doesn't require direct sun. Even works on cloudy days. Does require a slight push to get it going.

Love it great product. Once its set up properly, you can give it a spin. I had this unit running during sunlight mid-day, RPMs in 3400 range Avg. WoW!!
