"This thing is a blast!
I bought one prior to taking my son to a cub scout outing.
The first tries were less than stellar. This was not the PowerUp's fault...we just made a poor airplane - the boys made suggestions on how to improve the plane and through trial and error we tweaked the plane into a flying machine of high quality. Our first flight was mere seconds, but over time we increased the flight time on the plane we made to almost 3 minutes.
After that, they spent hours chasing after the plane.
Recharge times were fast enough to keep the boys happy, and the ability to discharge the device was very helpful at lunch time.
As far as durability: 12 boys ages 10-12 years old bounced it off of a few trees, pulled on it, hit the parking lot a few times, and even got it stuck on the roof once. (I know it says indoor use, but...) The PowerUp 2.0 is still running.

My son now has a new goal in life, he want to be an Aeronautical Engineer. I am now happily subjected to my 11 year old telling me about how ailerons work and how we can optimize the airfoil effect of a paper airplane wing to best increase lift.

Some toys are worth more than what you pay for them.
Thanks PowerUp."
