The media could not be loaded. Right off the bat, this item is cheap. Worth maybe $5. The paint is dripping down the sides, it feels flimsy, and it sometimes shoots the ball off the track. I have seen videos of a similar device that is lighter color with a thicker base, it was completely silent. This one is extremely loud (video included). It came with no paperwork. Due to this I didn't know it had a battery, or a light to indicate if it was charged, thought it had to stay plugged in (came with an 8in cord). Also didn't know that you are only supposed to run one ball at a time. Even when doing that a ball would shoot off track after about 40 seconds. I bought this as a gift, but had to get it back to return this junk. So disappointed.

Unit is flimsy and balls some times miss and fall out. Bought 2, one worked pretty good the other one missed sometimes. I guess it's a hit and miss, but keeps people occupied for at least 10 minutes. Also a bit noisy, that kind of gives it away that somethings up.

The only problem was it made a lot of noise, I didn't see any reviews on it, and it came with no directions or explanation of operation so I don't know if this problem is normal, but it may serve to say this item makes a noise when operating which takes away from the intrigue of it,

I bought this for a specific purpose. It is super cheaply made and super loud. It only works for about 20 seconds before the ball flies off of the track. This was sold to me as “New” but i opened it to find out why it was so loud and there was hair and fuzz wrapped around the motor and a dead bug. So they sent me a used one that was someone else’s junk that they had sent back. DON’T NOT BUY THIS!! IT IS TRASH!!

There's a lot of electronic noise from this device (more than you expect!), but that is understandable. The frustrating part is how often the marbles jump out of it - you can't leave it on while someone walks in, it'll lose the marble before they get there.

Fun

Poor gift. Noisy motor in top piece to move balls. Very loud -- covered up in video by music track. Not magnetic -- just a tiny rubber wheel in the top piece that launches the balls. After a few minutes, balls start launching out of the unit. Disappointing...

My kids loved it. I could have been more impressed with it. I thought it would function without power. But it kept them entertained and that's what matters.
