I am a copywriter and for this reason I decided to use this service as a business assistant. We all know that you can do viral advertising in the Instagram and this is the best social network to promote your services. I took advantage of using this service and did not regret. The interface is good, settings are easy and simple. You can select subscribers by gender, the number of photos and other attributes. You may add more than one account for Instagram. If you would like to have the target audience, you need to choose a donor you need subscribers from. That's what I'm doing. I have over 10 of them. Service subscribes and unsubscribes, puts likes and writes comments, and that's what interests the target audience. The cost is not much, two trial days are available for free for new users.
