Bought this as a gift for my Mum and Dad, and had the dubious honour of setting it all up for them. I needn't have worried, as it's pretty straightforward.
I left the units on charge overnight before I connected it to their telephone line and programmed all of the settings. The ability to 'copy' across from one phone to another is a great feature, and saved so much time setting up.
The phones look good, the range is great, and of course you only need to make sure that the base unit (with the answering machine bit attached) is near a phone socket and mains supply.
All of the other handsets can be situated anywhere, the only requirement is that there is a normal mains socket near the phone, and that each handset is within range of the receiver (base unit). In a 'normal' house, I wouldn't anticipate any problems as all of the handsets worked for me first time.
Mum and Dad found the large colourful clear display and the 'night' feature really useful. Dad is partially disabled and tends to slide off to bed early in the evening. We have programmed the upstairs phones not to ring after 7:00 pm, and come back on at 9:00 am. This means that Dad is rarely disturbed by the phones ringing downstairs when he's gone to bed, but the phone can still be answered upstairs if you hear it ringing downstairs. As I said, simple, but a great feature.
Previous models were criticised for the lack of ringtone selections. I can't really comment because I'm not in a position to compare, but I will say that there are about 20 to choose from, one of which is a Christmas tune! At the end of the day, this is a telephone. 30 years ago, all telephones sounded pretty much the same. 'Ring Ring' I think it was, so I think it's trivial to get too hung up over the style and number of ringtones available. (Pun intended). Life's too short.
On the subject of handsets, I believe you can add a further two to this unit if the four supplied are not enough.
Finally, if I had to gripe about anything, it would be the very shiny black finish which would have the likes of Hyacinth Bucket (pronounced 'Bouquet') polishing the phone every three or four minutes as fingermarks appear fairly easily. Also, a bonus to others but not to me, is that I waited six weeks past the anticipated release date for this phone and paid full price, only to see now that it has dropped £30 in less than four weeks of its actual release date!
All that said it is a very attractive phone, and I have been so impressed with it that I am seriously looking to buy one for myself.
At £130 it was a very satisfactory purchase. At under £100, it's a bargain! So buy one. Or two.
