This alone will give the launch/Keon longevity - it cannot break down nearly as much as it did in the past if it wants success.
@Hahn81 - about the speed - it looks like the Keon has longer stroke length, so that will always make most toys appear slower if its trying to complete a full stroke.
I’ve watched its ‘fast’ mode and it appears to employ the same techniques that devices like the Handy have where it will simply shorten the stroke to keep up with action on screen (the launch could only do that up to a point)
Time will only tell when we try these with synced videos, but thats my take on how it appears
