Considering that Shapeways is the best 3D printed jewellery manufacturer in the world, one might hope their app would be professionally made. However... unlike some better apps I have seen, the SW app does not connect your product descriptions and prices so that updating them on SW updates them on your Shopify store. You have top do that using a spreadsheet that you download and upload. I made the big mistake of using the SW app soon after they launched it when some details were not synched by the spreadsheet. Updating to the latest version of the app would overwrite many of my changes. Now I have to check every order that comes in to make sure the materials and item# are correct before manually confirming the order. If I accidentally misread something it is possible I could confirm a solid gold order instead of a gold plated order and stuff up my profit margins for a long time! It would be sooooo good if the SW description and price changes could be pushed automatically to Shopify as I have seen done (by SKYOU for instance). Apparently they do not consider Shopify store owners to be important enough, or else they are surprisingly technically incompetent. I give it 2 stars because it does the minimal connection an app like this can do really. It would be hard to build in less functionality and call it Shopify integration at all. As far as I know the app has not been updated in the last year or so.
