I can live with the lack of features/filters, but if the data itself is incorrect, then there isn't much point to it. When searching for companies using a specific tech (e.g., ecommerce tech), the tool returns companies like Hyundai, Washington Post etc. Initially, I thought that they may have a separate store somewhere and checked on Builtwith, Apollo etc... and most of them (~80%) didn't. I am not sure how the data is scraped but from a prospecting standpoint, you're better off using Builtwith, Apollo (or the hundreds of similar tools not specific to e-commerce).
