It's good, but it's expensive.... but good :-) !!!
What do you like best?
Good support and above all the desire to please and assemble the system. Different meetings every week to see what needs we had, constant questions of whether the product satisfied us, constant emails of whether this or this utility would not be helpful, ... the truth that at the support level are more than excellent.
If the system is attractive since it is focused on the client being able to design at 100% the characterization aspects of their products as they wish (labels, caps, pins, lighters, T-shirts, ...).
What do you dislike?
The only bad thing is that maybe you need some more source (which has a few), your 3D preview of the "final" product could be something better, and finally the integration with sales system such as woocommerce could be much better. However, I provided it for PrestaShop and it worked very well. Finally, although its support and attention is excellent, this is related to its excessive price ... it is very expensive, at least for the year that is what is contract.
