When I tried out the original Kica fan, I was not sure if I would love it. It was odd to have an electric, powered dust blower that was much more expensive than the spray can kind. Over the past year, I found many uses for it:
1. Dusting the inside of computer, laptop, and electronics
2. Dusting window ledges, TV, stairs, and behind my work desk
3. Playing with the kids by pointing it from a distance at their hair (you should never point directly at their face if they are sensitive to it)
Battery had lasted a long time without needing a recharge.
The new version is nearly the same size, but packs a noticeably more powerful motor at a LOWER noise level. Battery has been increased for a slightly longer runtime. The nozzle head is, like the original, removable, but slightly larger in diameter. The new model provides 2 heads: one that can help get into smaller cracks -- like keyboard keys.
