Wish I had found this sooner - it works!
on 18 May 2017
I installed this one week ago.
My nuisance calls have reduced from at least five per day to one (which I blocked immediately) during the whole week.
It could not be simpler to install, and worked immediately, and there is a video on YouTube showing exactly how to do it. The only confusion was that I thought the blue light round the "block now" button should be on permanently, but it only illuminates during an active call.
The unit is about 125mm wide diameter and 25mm deep, so unobtrusive. We have a 4 phone hands free system with a base station and three remotes. The Shield must be connected to the base station. However, unwanted calls can be blocked from any handset by pressing #2 to add the blocked number to the memory. Generic unwanted calls such as "International" or "Withheld" can be blocked by entering a code using the base station handset. If you block all "Withheld" numbers you will need to tell genuine callers such as doctor's surgeries so they can enter a prefix to allow their call through. It is all covered in the instructions.
