I decided to buy this unit for my parents who struggle to hear the telephone ring sometimes. It is exactly as described, very small and simple to connect. In fact I have uploaded a picture of it next to a highlighter pen to show just how small it is.
What I really like is that it does not need any mains power so there is no cables everywhere. I simply connected it between the wall socket and the telephone and it works, no issues or hassle. And the size means it can be tucked in behind the phone. It comes with double sided sticky tape as well so can be fixed it to the wall if you want to.
It gives out quite high pitched tone when ringing making it almost impossible to miss the call. But if that is irritating, you can turn the volume down (note the volume adjustment has only two settings – high and low, it’s not the usual turning switch you might expect) and the flashing light will notify you of the incoming call. The light is quite small but more than adequate for the job.
I don’t usually leave reviews but I was impressed by the simplicity and benefits of this unit and though maybe this will help someone. Well deserved 5 stars.
Also I have come across a few similar units on Amazon but having done a little bit of poking around it seems that connected essentials specialise in this type of products so I was reassured to buy it.
