Really expensive, limited and basically feels like a con!You cant add an English phone number or send by text as it only accepts american phone numbers (they may say it does but you cant get past the phone field with an English number)! You actually buy a redemption to code which you can only use against 1 invite at a time so you cant interchange your invites. When it comes on a smart phone the invite is distorted and doesn't have all the details or chops bit off! $29.99 for 40 invites is a waste of money! I haven't even got to the experience of it being blocked or going into junk email yet! Wish i hadn't started with it.Advice - use someone else.
