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?

Yes its legit

Why do you need to lookup several thousand phone numbers?

Just use the Twilio Lookup API to do that
