Field-tested by my team. Hours-of-operation field meant my SDRs called during open windows. Bought it while building a high school prospecting workflow for India. One column I'd add next refresh: secondary email.
Ran the CSV through our deduper first. Hours and GPS were the missing pieces in my last vendor's file — this has both. Bought it as the seed list for a high school outbound push in India. Money well spent.
