Might I suggest perhaps reshooting the video, possibly in an applicable environment to the product, with all the changes suggested above (especially the twirling and putting the shaft toward the camera).
Make some additional changes such as:
-Double Check some facts first
-Updated price, or rather source for lowest cost
-Change terms, ie 'Marketing Scam' to 'Marketing Gimmick'
-Proper Pronunciation of terms such as 'Ferrule', 'Conical', 'Z-Shaft', '314'
-Explain Conical Taper, as oppose to Pro Taper, to those who might not know it.
-Maybe explain how Low Deflection is achieved, and greater detail into its construction, like the sound dampening foam, and lower end mass.
Maybe write what you're going to say ahead of time, on a card or script, that way it seems more coherent.
Again, as Hu stated earlier, This does not mean that I think the video was bad, just that it could be better. Please accept this as hopefully constructive criticism. You made a very good effort and overall a good presentation. People with no knowledge of the OB-2 should gain some knowledge of it from your review. Thanks for putting it up!
just messing with you, nice job.
