I have been using Autofill Magic for a couple of months now and i absolutely love it. Before that i've tried Magic Submitter, SEnuke, Ultimate Demon, Sick Submitter, Licorne AIO, Zennoposter, Serengines for GSA and semi manual form filler tool for Xrumer when it was available few years ago. These are good tools for creating web 2.0 properties but I've always wanted to have better success rate.
With Autofill Magic I am receiving a high percentage of the submissions. It helps me to create quality web 2.0s quickly and efficiently, and from my experience, most of them stick pretty well, which is huge. It is very accurate when filling forms.
This tool is great for my tier 1. You can post several times to the same web 2.0 site and create link wheels, link trees or link pyramids very easily. I also use it for building some high quality, solid web 2.0 networks for my money sites.
Autofill Magic is the best tool to create tier 1's since most of it's web 2.0's are top quality and you actually control every step when filling forms. This tool saves me time and money. It is extremely easy to use. It has great support and many detailed video tutorials.
Autofill Magic team releases some cool upgrades, i'm excited to see the improvements. I would definitely recommend Autofill Magic.
