This guitar is almost perfect.
The fretboard is just as regular nylon strings guitar, portability is as expected.
It should be used connected to an amplifier as without a box there is not much sound it naturally can produce.
However, for me as a finger style guitar player, the only down side of this guitar is the absence of an arm rest. I wrote to the manufacturer, and they told me that due to the construction of the Ultra-Light Nylon, the arm rest is not able to be attached to the body. This feature is only available on the Pro Series Mod X or the Speedster Series.
I think the arm rest is more needed for the Ultra-Light Nylon than it is for the other models as they are electrical guitars with narrower neck less suitable for finger style.
Other than the absence of an arm rest I really like the Ultra-Light Nylon, it is very portable, the playability is good, sounds great when amplified, suitable for practicing anytime anywhere.
