The problem of nuisance calls in the US is at an all time high according to the makers of the country’s leading call blocking device which recently sold out within seven minutes on QVC.

CPR Call Blocker appeared on the shopping channel last week and members of the public snapped up thousands of the call blockers, with the product selling out within just seven minutes. In response to the overwhelming demand, CPR Call Blocker are releasing another batch of their best selling product to go on sale on QVC this Saturday at 09:00 EST.

Bryony Hipkin of CPR Call Blocker, comments: “After seeing how popular our last slot was on QVC we have decided to go back on air this Saturday. We didn’t even make it to ten minutes last time before we had completely sold out which shows how great demand is and unfortunately, how big the issue of scam and nuisance calls is across the states.”

Bryony continued: “From our previous work across the US it is clear that the problem of nuisance calls continue to be a major issue for people across the country. We often find that despite their best efforts, nuisance callers continue to plague people in their own homes.

“Our YouGov survey from earlier this year showed that 60 per cent of Americans claim to receive repeated calls from the same companies, even after they have been asked to stop, whilst 32 per cent receive more than 20 calls every month. Our call blocking technology can rid people of this inconvenience by blocking them at the touch of a button.”

CPR call blocking devices plug into any landline and feature a ‘Block Now’ button, which ends an unwanted call and permanently blocks the number. They come pre-programmed with up to 5000 known nuisance callers and have the ability to block up to an additional 2000 numbers.

The CPR suite of call blockers is available from and
