I bought this to get templates for my Supernote. There are a ton of options for all of my devices. The Supernote png is not sized for the new Manta. I was able to resize the pages myself and they look amazing on the device. The only other minor inconvenience is that it isn't always clear what I had bought access to and what had an additional price tag on it. Overall, these are minor things and I am 100% enjoying the amazing variety, clean graphics and customizations that are included. I highly recommend for anyone whether you have one device or many that you are downloading for!
