I was expecting the same when I saw it.
Yes, it is very light and not bulky - I don't notice it to be hones but its always there for when I need it.
It will help to protect the back as the iPad back will never make contact with any surface.
It doesn't dampen the vibration. I have had the Air 2 Boomerang since Monday but I have been using a Boomerang on an iPad since May last year.
Thanks for the info.
Where did you get it? Website seems to be in USD.
