Absolutely love this phone. When we moved we had to get a new home number, and it used to belong to a Jewelry store (3 years prior!). So on top of the ridiculous amounts of scam calls and telemarketers we got, we now get scam calls for a business that hasn't been open for years. I was able to block 25 but I had hundreds. We desperately needed a phone with a blocking feature, and Panasonic was recommended to us by a neighbor. Since getting the phone, I blocked 8 full numbers. I also went through my list of blocked numbers and blocked all the area codes they are calling from. Now I may get 1 or 2 a week, from an area code I haven't blocked yet. On top of the great blocking feature, it has silent mode. You can set certain times for the phone to not make a sound, like my cell does. It's great for the handsets that are in bedrooms. It also has talking caller ID like my old phone. You don't have to go running to see who's calling if you aren't near it. I couldn't be happier with this phone. It's stopping me from losing my mind from scammers!!
