Zen Go Synergy Core : Great features in problematic package

I'm satisfied with the features and performance as there are no other options including DSP in this price range. But it comes with drawbacks as I think the interface design is flawed

* I don't like handling at all, especially because the unit is placed on my desk. I'm looking at it at an angle from 75cm distance and the display is useless cause it is not very good quality and in this scenario is completely unreadable. So whenever I want to change volume or anything I have to stand up to look at the display from above to see anything which is annoying. It cannot be placed vertically as the headphone outputs are on the front side

* I personally don't like the control scheme where you have to push buttons to switch mic/monitors/headphones volume and then change it via the control wheel. It's simply tedious also because there are only two buttons for 2-headphone-outputs/2-mic-inputs/monitors-outputs so the buttons have to be pressed more times to find the thing you are looking for. I think the scheme of classic interfaces where you have more knobs with dedicated functions is soooo much better than this. Looks cool maybe but is painful to use

* the unit shape prevents it from stacking. I you want to stack it you have to place it on top of the stack

* software is ok but it seems very rough around the edges and I encountered some bugs although to be fair Antelope is releasing updates from time to time

* I'm satisfied with sound quality and dsp effects

Overall I'm thinking about selling this unit cause I'm not sure DSP effects beat the day-to-day usage problems and the overall experience is not very good for me. Especially compared with Motu M4 which I bought for my second computer - that is a completely different story and I love that unit! I can easily work around missing DSP effects in Motu but I cannot work around usability of ZenGo
