I would give this service 5 stars but they lack a couple of options I want to use. They want to provide people this service all in simple one button, a sort of apple of instagram growth, but I would like a little more flexibility. Support staff are nice and respond fairly quickly. Definitely grew my fan base and the followers are all quite active which is nice too. Would recommend.
Tip for consumers: It doesn't work for every niche (I tried on my personal), but works really well for brands and business-like accounts.
