On the pro side this is a great idea and has a very nice looking layout. The one thing I wish that I would have known before investing time in getting this app set up is that it's still a bit of a work in progress. The developers have been helpful and responsive, but I've run into a few hiccups which had to be handled manually. Once it was set up I learned that people could only select 1 variant per product for their gift sets which is a problem for my business. The app developers say that this is going to be addressed in the future, but that will be too late for holiday orders for my biz. I think this will be a 5-star app in the future, but currently it's not something that's fully functional right out of the box and I needed it to be.
Thank you so much for the review. Just in case it's of any help, you can allow multiple variants to be selected, you just have to enable the 'Show variants separately' option. I know that's not always a perfect solution but it's available now if you wanted to give it a go. As you mentioned, we're currently working on another method of allowing it that works with the variant drop down menus.
