I've used in the past - 1 and 1/2 year back, and it does work - provided that if you used the right proxies when using along with the software. So the tool was able to help me go up 1-2 pages up the SERP for specific keyword being searched on the search engine. The key is to use rotating residential proxies along with the tool, and when you run the tool for 2 weeks straight, you'd see your ranking climbing thereafter. Please note that I am unsure whether it still works, as this highly depends on clean or very diversified residential proxies to work. If you do not have good proxies, I do not think the tool will work too great.
