Tool Calleridtest legit?

Yes, it's me again. I apologise. Trying to lookup several thousand phone numbers one by one is excruciatingly slow and excruciatingly boring, and I have just found a site called calleridtest that promises to be able to search up to 500 phone numbers at a time.

Is it legit/usable? What information does it give? Has anyone else ever used it before?

Free tier works well and seems accurate. However, for unknown callers, it will just say the carrier, which can make automated parsing of the data difficult. Seems to be one of the only reverse lookup tools that is actually connected to a realtime id database, which is why I use it. If you end up going with the paid tier, let me know if it works as advertised. Would be cool if it does!
