This phone blocker seems to work well except that when someone calls and they press the zero button to make the call go through the first time, when ever you answer that call, the box continues to ring four times after you answer and start talking and you can hear it through the phone. This includes both the new version 2.0 and the older previous version.

While this product does indeed stop incoming unwanted calls, it has a major drawback in that it does not support calls that are desired. Several of my legitimate callers pressed "0" as instructed, and the machine did not pass them on to the telephones. It emitted a warbling sound and the phones did not ring. By the time I could get to the unit from another room, the call was terminated. I had to "review" the list of incoming calls, recognize my desired caller, and then select "accept" in order for them to come through to the phone. There have been several of these instances, and usually if a caller is once treated this way, all subsequent calls are met with the same treatment. As I am not always home, many of these calls were not known to me until days later (for my landlord, it was a month later), when I would be fortunate enough to be seeing my caller in person and they would tell me they had called and did not reach my voice-mail recorder.Read full review

Decent unit for the price. If a caller is not on the white list your phone rings once and the caller is given the option to dial 0 and the Sentry unit will then ring five times. There are issues with Uniden and Panasonic cordless phones, but they can be worked around. The fastest way to review calls is to hit the home button then the middle down button. Most recent call is #50 oldest call is #1. Version three is out and while I won't upgrade I would not buy a V2.

We LOVE this call blocker. We tried another brand but it was cheaply made, buttons on it wouldn't work. I told my hubby that it's Sentry brand and I assumed that meant the big company that is Sentry. Anyway, it is great!! It captures robo calls without you knowing it. The phone doesn't ring and supper or tv shows aren't interrupted. We highly recommend it to everyone out there who needs a good blocker at a decent price.

This is a telemarketers nightmare. Without a doubt the best call blocker I've ever used. I can't say enough about it. If you're in a hurry, get the Version2. If you can wait a while, wait for Version 3 (Has new features). I use Version 2 and when Version 3 becomes available, I'll switch to that and give the v2 to a friend.
