I've used a previous version of the CPR call blocker for several years, but as the spammers get more sophisticated it was becoming less effective. The V5000 however, has suddenly cut the number of junk calls we get by about 90%. It doesn't stop some calls which appear to come from our local STD code area (but are usually from Asian call centres), or some fake mobile numbers, but being able to immediately block a number remotely, by keying #2 from any handset, is an excellent feature. Well worth the money for a much quieter life!

The 2nd CPR blocker I've had. The 1st one became full after many years of blocking! I wouldn't be without one of these and I get a perverse pleasure out of seeing a blocked number showing on my phone, that can't get through!! A "must" in these days of scammers.

This is a brilliant little device. Really easy to fit, easy instruction leaflet comes with it, and it's worth it's weight in gold if you're having lots of spam phone calls. I've blocked 11 numbers since fitting it and now I'm not getting any spam calls. (I was getting about 4 a day) What's also brilliant and useful to mention is that my landline isn't one that shows the number that's calling but I do have caller ID in my phone package (which is what you need to make it work) so now I can see the number that calls, if I don't know the number I answer it and if it's a spam call I just press the block button and cut them off and then they can't ring again. I love it! (I even said "you're about to be terminated!" being a fan of the terminator movies! lol I highly recommend this product.

Update: I've now blocked 24 numbers, I have a "live" not robot caller spammer calling every day from different phone numbers, today I blocked him 13 times! It's very satisfying to block him but I'm astounded he keeps phoning when I am clearly not going to enter into conversation with him or buy anything. I looked it up online and apparently when the same person uses different numbers its called ID spoofing. Hopefully he'll run out of numbers soon lol. Great little device, very pleased with it.

We bought this five years ago. Has an instruction booklet but it's dead easy to install and use. Comes with a good many spam numbers already installed but whenever you receive a new spam number you just hit 'Block Now' and that's it. No more calls from that number. As spammers are always coming up with new numbers you will still get some spam calls but it definitely cuts down the number of them. If you block a number by mistake you can easily unblock it. You also have various options: you can block all withheld numbers (but may not a good idea as hospitals/surgeries often withhold their number) or can block international numbers. Would recommend.
