Review on 🚫 Sentry 2.0 Phone Call Blocker: The Ultimate Solution for Blocking Unwanted Calls by Ann Montana

Of course I'm exaggerating, but not by much. I'm a technical consultant working from home. My phone rings about 10 times *every hour* during business hours and at least 9 out of 10 of those calls are spam. This device is the sentinel of sanity. Blocks 100% spam, cold. And just for reference, a CPR call blocker with a big red "BLOCK" button, which is Revain's "choice" call blocker, is as useful as a piece of rock (yes I have it too, bought it from Revain too) . Only known numbers are blocked. Maybe spammers on the planet of the people who designed this device only call from valid landline numbers. Unfortunately not so on planet earth. Take this one instead. And this one is cheaper than most other blockers.
