Bought to replace terrible BY Synergy 4100 DECT phones.
The photo does not do justice to these phones; the red colour is surprisingly attractive, so don't let that put you off. They are also pleasingly small, yet ergonomic. They fit comfortably in the hand and against the ear, and buttons are in just the right place.
Ringing volume is perhaps a little quiet, but it's still loud enough to hear one floor away, but not over the sound of a vacuum cleaner. Still, if you're expecting a call whilst vacuuming, you can bring one of the phones with you.
The speaker is clear, there is no crackling, and the hands-free speaker volume is just right. Display is a little cramped but when caller ID is operational the display flashing the caller name (if in the phone book) and then the number; the names are harder to read than the numbers.
I have no major gripes about the phones at all. They may not have all the features of the old BT handsets, but these are reliable, have a good range, fit properly in the cradle, charge quickly, have clear sound, and just do what they were designed to do.
Can't really fault them for £26.
