As the other people have said before, it is a great entry to the Line6 Helix family. It sounds great and it is easy to use. The build is stirdy, especially the parts you touch with your foot. However I gave the quality 4 stars due to the knobs and encoders being a bit wobbly and I'm not so sure for how long they will last. Otherwise the design seems to be very well thought out.
The other problem I had with it that the FX-loop didn't work so well in stereo, meaning that after placing it after the stereo effects they collapsed into mono.
Finally I would give my 2 cents from the blindness perspective. I know we are a tiny minority and for most of the people it doesn't matter, but I'm not the only blind person who buys from Thomann, so maybe the following info can be just a bit useful. :)
It is quite usable thanks to the physical buttons, knobs and encoders. The latter ones do click when turned, so you can understand more easily where you are in the effects chain or in the menus. Of course reading the display is a problem but the manual explains them quite well. The only issue I have with it is that each effect modeled can have a different set of parameters and when you cannot see the display and they are not listed in the manual, it can get confusing quite easily. Fortunately trial and error when turning the knobs and listening with your ears usually helps. :)
