5* Rubbish !
Reviewed by Adrian on 20/12/2010
I bought this phone for my elderly mother and I have to say that it is completely useless !! Reason ? because the default earpiece volume setting is the lowest (why ?) and the phone resets itself to this setting at the end of every call (why ?). How ridiculous for a phone that should be designed for a confused elderly person with arthritic fingers !!!!!!!!!!! Of course my mum will never remember to press the volume button every time she makes a call - and in fact it has to be pressed not just once but 3 or 4 times to get to max volume.

Apart from that, the volume is not that good anyway, even on max, and also the ringer volume isn't that loud either, even on max.

Far better phone is my mother-in-law's Geemarc CL100 but a bit more expensive.
5* rectification of repeated problems
Reviewed by Peter Kenneth Johncock on 14/11/2010
after reading the reviews on the "big button 100" telephone there seems to be a repetative problem with button 8 and heaaring problems. Am interested in purchasing one of these telephones but has anything been done to sort these repetative falts.

5* Big-Up The Big Button 100
Reviewed by Mr. Alston on 09/09/2007
My 87 year old Mum has problems with her hearing, eyesight and has arthritis in both hands and her current phone was unsuitable. What with her fear of modern technology and a declining memory, learning to use a new phone was going to be a problem for her and a challenge for me. I searched the internet for suitable phones and selected the BT Big Button 100. As an engineer, I can appreciate that BT have designed this phone with the less abled user in mind. It's easy to handle & use and the contollable Amplified Speech facility is a blessing. The full Hands Free option, with the same amplified speech is a delight. Finally, it's Hearing Aid compatible too. Mum took to it like a "duck to water" and then phoned her friends, telling them: "What a wonderful new phone my son has just got me"! Well done BT, not only have you solved my Mum's problems but you've removed my frustration too....and all that for around the £25 mark!
5* Big Button, Big Help!
Reviewed by on 15/06/2007
My mum has had two of these phones over the last 5 years and only changed it because of the discolouring that occurs if it is left in the sunlight. It has been an invaluable tool for her as everything is so clear to see and so easy to use. Even I like to use it as the big buttons make dialling very quick. As for the debate on hearing aid compatibility my mum has had 3 different digital aids and has never had any problem hearing without having to use the amplifier. Overall I would like to say BT has a great product in the Big Button telephone and I hope they don't change it too much in the future.
5* A great phone for those whose sight isn't good
Reviewed by on 15/06/2007
This is a great phone for those whose sight isn't good. My mum is both registered partially sighted and has arthritis in her hands, but finds this phone easy to use and the shape and lightness of the handset is a big plus. I'd recommend this product for anyone with similar problems. Just a small point BT -I know not everyone's a techy, but it would be useful to publish the REN in the extended specifications.

BT Response. Many thanks for your feedback. The REN for this phone is one. For the non-techies REN stands for ringer equivalence number. A standard telephone has a REN value of one and the total REN possible on a BT line is 4, in basic terms, it is the number of extensions you can have. Once the REN value for a line is exceeded you may lose features from some of the phones.
4* BT Big Button 100 Telephone
Reviewed by Anonymous on 18/02/2011
I am just about to order my third phone as most of the features are great. Each previous phone has the number 8 sticking. The latest problem is the handset has died altogether, although the phone itself is still working.
As the price is right we will give this model another try and hope we have no problems.
4* mixed feelings
Reviewed by Joz Latusek on 14/12/2009
I like the phone enough to be buying the same model again. Sadly the one I bought in August had to be returned today with defects that have occurred in recent weeks. The number 8 button was starting to stick sometimes. And despite trying replacement batteries, the 1571 message tone and flasher stayed on even after messages were deleted. I am hoping this was a rogue example and that its replacement will last a lot longer.
