I had previously used the Nunchaku 1 for over two years and was looking for an upgrade. The Nunchaku 2 definitely delivered on all fronts!
At first I was concerned about the lack of buttons and having to use the built in tilt mechanics to change the wattage and other settings. However it turned out to be very intuitive and actually more convenient than the older model. The ability to use a higher quality battery was a plus too.
I have been using this kit for over a month now and would certainly recommend the Nunchaku 2 for anyone that was a fan of the first model.
