It's a really simple system to integrate with, and provides great support when it comes to customising your code. There isn't enough configuration options for some people but this can easily be solved by adding more fields in config. The lead generation form looks good too! Leadback makes my work easier, I used other systems before that was very hard going through hundreds of leads every week. The user interface of this product was very easy to use, with quick loading speeds as well! I am able find what i needed quickly without any difficulty or confusion at all!! It's price isn't too expensive either so it didn’t seem like an issue for me personally (at least not in my opinion). As mentioned above there were no problems that came up while using lead back but if you do have questions please feel free contact their support team via livechat/email etc they are great people who will help out.
