I like how easy it was to use this software - you don't need any coding skills! It's really simple but powerful at once time too; all data are stored online so there isn't much space needed either when using multiple computers or even laptops/tablets etc., great tool if used correctly!! Nothing i dislike about crab yet.. maybe more tutorials? But overall good product by far. Recommendation engine needs improvement though because sometimes recommendations aren't accurate enough compared to other programs such as amazon recommendation systems where they have thousands upon millions of users who rate products before purchasing them. For example one day my friend recommended me some books he thought would help improve his writing skill however after reading those book myself found out its not what im looking forward towards haha :).
