LOTS OF GOOD FEATURES
The BT 6600 model was bought for my adult son who is Aspergic & gets a lot of unwanted calls, so being able to block these is really easy for him but I had to contact his provider to facilitate the relative service which, with his, is free. There are a couple of ways that these calls can be blocked as I understand it; from the contacts list and when an unwanted call is received - not completely au fait with everything yet.
The keys are very clearly marked and a good size.
One feature which is very good is contacts; once on the main handset they are synchronised, so only have to be put in the once.
The screen is bright and clear and audio good.
The answerphone message can be personalised if required & the number of rings too before it kicks in.
The loudspeaker is a bonus so it doesn't have to be held all the while.
The instructions are a bit daunting initially but obviously only the features you want to use are applicable (and there are lots of features). Also the instructions are available online to download if, as in our case, the phones were refurbished.
All in all I would definitely recommend this model.
