Great physics demonstration tool. Leads to a lot of questions and a better understanding of per petrol motion.

Bought this for my son’s birthday because he was super excited about the concept. Opened the box, charged it up, doesn’t work at all. Magnet is insufficient to make the ball jump back up all the way so the ball just shoots off the rail and onto the floor. Bought it early before the birthday, unfortunately, so can’t return it, but complete waste of money.

Nice quality and works well - just as advertised.

bought this for my dad. has the same charging concept as apple mouse. overall its okay ^^

Charge doesn’t last very long.

After charging the device, I was unable to make the metal balls stay on track. It seems that the track is not aligned with the center. It is very likely a used device sent to me. Trace of dirt/food or something else is visible on the track very likely showing that the device had been previously used by another client who sent it back before it was shipped to me after repackaging. It is the first time, after many years and many orders on Amazon that I am going to send back this device. Device should have been tested before sending it. If it is a new device, as I was expecting, then I would not recommend its purchase .

If you're not a nerd or have potential to be, you may not enjoy it. I use it frequently. Love it.😍

I got the wooden version and it is hard to see/find the camouflaged on-off button. I took me a minute to figure out how to turn it on. Hint, it is a small circle on the top about a half inch behind one of the 3 supporting posts. Just quickly slide your finger over this circle to turn it on or off.Many reviewers complain about the charging plug being on the bottom where it cannot be charged without laying it on its side. I understand this concern but I think a charging plug being visible on the side would make it obvious that the unit is powered by electricity instead of being a real perpetual machine, so I agree with the manufacturer that the change plug on the bottom was the best location.
