I received the top and watched the main explanation video.
The value is mostly on the tutorial and all the tips on little details that make the performance look good.
For a collector, the top and box itself are a little disappointing in quality.
The basis of the trick is the usual magic levitation that you can learn on youtube for free.
So, I would say that if you plan to do this specific top levitation it's worth getting, but if you just want to get it for your collection or to learn how to levitate in general, it's probably not worth it.
To do it cleanly will require some practice and preparation, but the result is impressive. I will probably try it the next time I go to a spinning top meet, so you may see it in person.
If you want to see more magic with tops (including a different levitation), we discussed the show of French magician Cyril Harvey before:
