I use this for home practice, using a looper pedal has helped to improve my playing, a looper pedal with a drum machine built in has helped greatly with timing - even picking scales to a click track!
Whats great about this device is that you can upload backing track as loops and play along.
Overall it dose what I want it to - the only draw back and why Ive given a 4/5 for features is that I find the user interface a bit confusing, I think NUX could have laid out the controls a bit better, but that's not a reason to not buy this. When it comes to looping its as easy as a foot tap or two!!
There are lots of more options/features of this product I have not yet explored, its great to know they are their - its just a great value product. Feels as solid as other better know brands.
