Great customer support. They added a feature for us very fast so very impressed with that (ability to grayscale uploaded images).
However, the load time on the front end is very slow - 30 seconds to a minute and in some cases longer even with a 60 mbit/s download speed.
Lots of backend bugs as well - can't delete a product design no matter how many times I try, can't change a thumbnail image on one product after duplicating the design, often crashes and forces me to reload.
Would happily change my review to 5 stars once these issues have been sorted as it's a pretty good app at a reasonable price otherwise but currently very difficult to use and get up and running.
