Many as I have heard is not very happy with this service. But I'll tell you so, my friend recommended it to me. She is very happy with it and is in complete delight. I'll tell you honestly, I thought that all this is complete nonsense and just pumping money-but using this service, I saw a week later a positive trend and result. Many likes, my page has become more popular than other people I know. Cons in this service I have not found yet. I use it for six months and never doubted it. I have many of my friends "hooked" on this service and no one has yet began to doubt it and even more began to attract their friends and acquaintances. Thank you for this service-it helps people become more popular.
