    by Carol on 12/01/2016

    Bought this for myself as I couldn't hear my phone ringing and I was missing calls. The loud high pitched ringing is great and I can hear it even from upstairs or when I'm watching television.

    i bought this for my elderly parents as they are hard of hearing. really loud and lights up too. works great but you must connect it correctly. the cable supplied could do with being longer. i would recommend it.

    by Esther on 14/05/2015

    Bought for my parents who frequently don;t hear the phone. Excellent fast service from Hearing Direct as previously and ringer fitted quickly and definitely amplifies the sound! It has its own ring-tone so no choices there and initially I thought we would have to buy additional cabling to get the right connections but the connecting cable supplied was sufficient (if a bit short)

    by James McCartney on 14/08/2014

    Had a problem when we installed new and more soundproof doors... missed calls when TV was on in next room, or when we were 2 doors away in kitchen.... not that our hearing is below par. The penetrating high-pitched rings gets through all this. Problem solved.
