Good product slow delivery so order on time !
You have to turn on location services for the iOS app to work - why?!? - after that you can use it. Ordered the permanent ink, got skin-friendly instead, which is useless to me, I'm not a 12 year old child. Permanent ink is not an option for ordering, period. So, while it works, the junk app and the lack of permanent ink make it a total miss for me.
It's quite expensive and prints with a lot of stripes. Did buy it, but was very disappointed in the end, because the product did not print as shown in the examples.
My recommendation: Do not buy this one!
