Review Content Just what we were looking for! We bought this for an elderly friend who couldnt hear her telephone but since adding this to it, she hasnt missed a call. It has worked great for her. My mom can hear the phone now! The ring amplification is adjustable. My mom is so happy with this product because now she can both hear the phone ring and see the flashing strobe light when a call comes in. Since she doesnt miss calls anymore, we dont wonder if something is wrong at her house. Great solution for elderly parents unable to hear the phone! I purchased this for my 89 yr old mother who is living alone in her home. My sisters and as well as myself worry constantly when we call and there is no answer. Either my mother cant ear the call or she is just sleeping. It doesnt help that she is hard of hearing. After getting this product our minds are at ease..It is visible if she is sitting and direct line of her vision if watching tv... Or while reading or napping the loud ringer wakes her up. NO CALLS MISSED AGAIN! GREAT PRODUCT!!! Works Great! I bought for my 87 yearly mother who could not answer her phone because the ringer was too low she loves it and is now answering her calls. Good For the Hard of Hearing I have tried so many different things in the past, andI have to say that THIS IS THE BEST PRODUCT I HAVE FOUND!!!!!!!! I bought this for my 88 year old mother who is very hard of hearing. We live about 4 houses away from each other, so every night before I go to sleep, I call her to make sure shes ok. She could NEVER HEAR the Phone, so I would have to Get Dressed and Go Over to her house. Thank God, I have her keys because she cant even hear the doorbell. Well, when I bought this item, it made a World of Difference! She not only Hears it, but She SEES it when it Lights Up! Whoever invented this product, I would like to say, THANK YOU VERY MUCH!!! I HIGHLY RECOMMEND THIS TO ANYONE WHO IS HARD OF HEARING!!!! Perfect Solution I bought this product for my elderly dad who is hard of hearing and works outside in his shop. The tone is adjustable and he is now able to hear the ring easily in the shop. This product has made life much easier when I call to check on him as he answers the phone and I dont have to worry if he is ok. Fit what was needed Did what I needed it to do. Have a phone in the garage its very hard hearing it ring when I am in the driveway.
