I have tried this app with no problems whatsoever, The previous 2 reviewers, firstly this app is not a scam whatsoever. As for customer support i have contacted them several times today and within mins vi their fb page they answered my queries. I think the products are amazing, the product customisation is as easy as 1,2,3 no extra customisation apps that cost. I am not in any way affiliated or work for this company. But praise in this case is justified and please try it, you wont be disappointed at all.
