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

He had some time and just hooked up. Entering numbers that you want to accept or reject takes too long. It's easiest when the phone rings, then you can, but you have to be nearby for that. The most frustrating thing is that every time you want to check or do something you have to unplug the line and remove the batteries. The instructions say to do this when it freezes, but really EVERY TIME? It also tells the caller to press 0 if you're not a telemarketer and leave your message, and that doesn't work. It just depends on you. However, if you call back, you can leave a message without the caller noticing. As a result, I haven't received a single message since I plugged this thing in. If that is your end goal then you will be very happy with this call blocker but people you know might start to think that you are just some kind of jerk. Great concept, but far from perfect.
