I really like how easy it was when we were building our first ever ecommerce site using sellfull as my platform! It's very intuitive (even if there are some things that could be improved).
We had no technical issues while setting up or running this store - which made me feel great about choosing their product over other platforms out therseeeeere!! Honestly though? There isn't much "to dislike" here at all; they did an amazing job making sure everything went smoothly from start till finish :) The only thing i would say might need improvement/change maybe even next year after launch but not now -- pricing structure needs rethinking since its way too high compared tot he value add provided by such software :D.
