They changed the mango formula from the original. If you buy a mango pack with "5.0%" at the top right corner... you're probably getting a faulty pod. They constantly leak and its pretty annoying. The new mango flavor also sucks compared to the original.. I'm not sure why they would even change it because that original flavor was so great and popular. If they changed it because t was attracting the minor crowd... well the new mango is actually fruitier, but due to the leaking of EVERY POD that comes from a 5.0% pack it's not even worth it. I use my juul everyday, but if I can't find the original formula I'm no longer going to be buying it. I'm giving them 3 stars because the device is convenient. If they offered the originally mango pod it would be 5 stars all the way.
