I am a user (based in the Netherlands) of this software (and accompanying hardware) and have good experiences with the software and the support... both have been top notch.
Like stated downloading the software is for free so you can play with the functionality.
There's a large userbase on cnczone.nl (Dutch forum - but with the help of Google translate this should be "readable" in Dunglish)

Ps. I am in no way affiliated with Eding CNC nor the CEO, just found this post by accident actually, but I wish them all the best (in the US) based on my positive experience.
