T-Lock Call Blocker

Tried the parallel installation and it only worked occasionally but the series installation worked perfectly. Have had it in operation for about 2 weeks and have 16 numbers blocked so far. Unwanted calls have dropped from 2 per day to 2 per week and I expect further reductions in the future. Can't wait for the next election. I paid a bit more than the least expensive source by using Wal-Mart but their return policy is the best. I didn't need that with this product as it works fine.

Easy to hook up and works well.

This seems to work very well and is easy to setup and use. Probably took me only about 5 minutes. You do have to read the directions though. I would, and have recommended this call blocker to others. My phone only has room to block 30 numbers and this one says it can block 1500 numbers. You only have to push the red button when the call is coming in and it's blocked. Easy Peasy.

I cant get it set up it says push set button will see 1234567 then use hand set. Does not work on anything. I thought I could just push blacklist button when an unwanted call is ringing. That does not work either. Will return item

Completely useless. First scam callers defeated it by spoofing it to show "full", when trying to add from your caller id list, only allowing additions if you hit the red button while ringing. NOW neither of mine allow even this,

Plugged inline to phone using Ooma. First set to block numbers with no ID. Blocked the doctor's call. Turned that off and blocked my daughter. Phone shows that her number ID is coming through but will not let call through. Returned.
