Their site claims an adult must be available to sign for the package. We were going away last weekend and left a little not on my door in for the delivery person if they came while we were away asking them to leave with my adult neighbor, they’d sign for it. Well no, they don’t reputable signature which means they left it in my mailbox all weekend. I live in Buffalo my and it is COLD here so this package sat freezing and frozen for 3 days and these are garbage now. They won’t assist me. They said it’s up to the delivery service how they’d like to deliver. Um... your website says an adult MUST be available to sign for package. So the way these people verify if someone is 21 is by them clicking that they are 21. This place clearly will fill and send to anybody as long as they have clicked they are 21. This my friends is exactly how these devices get into our children’s hands... First time customer... and also a last time customer!!
