I was thrilled to find this product online, though not being allowed to use my PO Box address caused some major confusion on my end and I don't understand why they won't send to PO Boxes. In many cases, PO Boxes are more secure than most addresses. Anyway, the vapes are fantastic, the flavor is amazing and they last a long time before needing a charge. Love, love, love the Elfbar... especially the Malaysian Mango!
