The ability to create custom designs within seconds, without having any design experience or knowledge about designing was impressive! It's not too difficult for someone with no previous technical background in software development but basic computer skills could easily do it as well (even though there are some advanced features that might be overwhelming).
There were times where we had trouble figuring out how something should look like because our product designer didn't have enough information from us regarding what exactly he wanted; however after several days/weeks they would come up with an idea which looked good so far - sometimes even better than ours :) So yes definitely try this tool if you're searching somewhere between cheap price options while still getting your own unique style into things! We solved all problems related to fast prototyping by using their online 3D printing service called "Print Factory".
