I like that this is an open source software, meaning anyone can contribute to it as well! It's also very easy to use even if you are not familiar with R or Python programming language (I'm both).
There isn't much of anything bad about shapelet either - good documentation available online in many languages including English; great community support through Slack & GitHub issues page etc.; fast response times from developers when questions arise via Github tickets/issues pages ; nice visualization tools such has Tableau Desktop which makes data exploration soooooo fun!! We've been using Shaperotio since we started our project last year at Vodafone Kenya Limited where we're working towards improving customer experience by providing better services across all channels within their ecosystem.
