I bought the 3 foot metal coffee table version, you can get a sweet ass 4 foot, hardwood version for like 10 grand.

It is legit though, looks even cooler than the videos in real life, and it will catch your guest's attention every time, they'll sit and stare at it. If you're artistically talented you can design custom patterns, and there's a big library of user submitted art available.

It has been pretty reliable so far (1.5 years), haven't ever had to open the glass to reset the ball or anything. Sometime the app controls can be kinda flaky, and one time I did have to unplug it to get it to hard shutdown and restart.
