I love how clean, simple to understand documentation there are! The most helpful part about this product was its ability not only extract leads via API calls but also able make an online store by creating own virtual products which have specific information of those businesses or any service we want (via their api). Not so much like some other reviews where people said it can be less reliable sometimes since they're still workin' out bugs here nthere - But overall i think all's well as long you've done your research first before hand. Definitely try if u haven't yet cuz trust me guys-it'll really gonna benefit yah!! Lead generation/marketing campaigns has been one way from my daily routine now after using global hop software :) Easy accessable tool makes lead gathering process easier than ever :)) This will surely enhance our marketing strategy greatly because every business needs sales right? With great results obtained through these platforms am sure more companies should implement such tools into everyday routines ;) The most helpful feature of HopSDK, has to be its API support! I love being able get access not only through their RESTful APIs but also using X-API's which are really great too - they're easy enough use if you have any Java or python background at all (which we do!). There isn't anything bad about this particular product as it does what i need without me having much coding knowledge needed either :). Using hopsdk allows us so easily extract info from various websites/blogs etc..
