I must correct myself (regarding my previous review -below-): I found out that if I successfully create a field set and I publish it, it works as advertised, in fact it looks great and although is a little complicated and not too UX friendly, it does the job very well. But the code I introduced in my product liquid template went missing, like it was erased, and that caused my fields to disappear form mu published site. I tried to repeat that event just to prove my thesis but I haven’t been able to. I'm 100% positive that code went missing without my intervention. I’m bumping it to 4 stars (not 5 because I’m not certain it won’t happen again and reliability is a big factor for me). Original review: If you want to see how it might look if it actually worked, then go ahead and install this app. I installed it a couple of days ago and after lots of hour of work it looked very nice, but today is just not showing none of my fields on my online store. They just won’t answer via human support, they just send some robot replies saying "read this", "go there", "create an account", "wait for a ticket" and all that runaround. It's a shame cus it really did what I was looking for. I'm sure they want me to follow a support protocol, but after crashing as it did, I don't think it worth the shot.
