Not a specific yoyo promo
But by a yoyo company
The shutter is pretty nice
This was funny hah
YETI VIDEOOOOO!!!
Prestige Video is a close second:
I got the half blue half violet shutter for my birthday on the 12th -officially 16 now! HOLLA!!!- but haven’t opened it yet. Can’t wait!!!
These are both older, but I’ve always liked “Revolution in Prague” by Anamorphic/Vashek (promo for the 888) and “Skyline” by Miguel Corea/Yuuki Spencer (promo for the Skyline). I think “Revolution in Prague” was the first video I saw that blew me away with both the video production and the tricks:
Not sure if this is really a promo, but it definitely inspired me and made me get my first KLR 
The YYJ Theory video is pretty freakin awesome.
Eric koloskis Diamondback vid.
Not a good vid, but some killer tricks!
that one is my all time fav also.
and this one;
You’re kidding, right?
You dare mock Grant Johnson’s killer photography skills? Other than the Prestige vid, no other video is as epic as Eric Koloski’s Diamondback.
I felt that the camera was too stiff and even though the graphics were better than par, it just didn’t make me feel anything -fun, seriousness, excitement, etc.
