Shortly after acquiring the product, one of the handsets failed. BT advised me that it was a fault and that I should return the set to Amazon. I am pleased to advise that Amazon sent a replacement complete set as soon as I had advised them of the fault and I then returned the faulty set
One of the reasons that I chose this model was the facility for downloading contacts from a mobile sim card. There was, however, one problem. It appeared to limit the number of telephone numbers to two per contact and unlike my previous cordless phone does not show the number when you select a contact from the address book. Therefore unless one selected the option to display the detail, one could (for example) ring a home land-line when one wanted a mobile and vice-versa. In one instance it downloaded a number in the fax field, which is of course singularly useless. One had to edit the entries one by one, which is of course somewhat time consuming and partly negates the advantage of being able to download contacts.
In all other respects it operates satisfactorily.
