I like that it's easy to use for most customers; however some of their UI could be improved by adding more icons or making them bigger/more visible in general so they are easier to see when using an iPad app rather than having users zoom out all over again every time you open up another page with new information! Also sometimes there can get stuck if your internet connection drops while trying to load items into inventory which causes errors but not always - just depends how long things take before loading properly after reconnecting back online etc.- Sometimes takes longer then expected as well once connected due to large amount data being transferred through server from different locations around world at same moment.
