Fantastic phone. Replacing many useless BT, Motorola, Philips and Panasonic handsets. All with their different good points and all with their faults or failings - non satisfactory.
The SL565 was easy to set up, is easy to use, looks fantastic and has features not found on any other DECT phone.
The Bluetooth feature is a blessing when transferring data from mobiles direct to the phone book - saved hours of typing.
So far I have found nothing that I dislike and everything that I like!

Good points Easy to set up - worked straight from the box. Feels good - not heavy but robust. Easy to input directory and copy to all the handsets. Sound quality and range very good - main reason for buying this set as on previous sets the quality varied throughout the house. One very good (and undocumented) feature is the ability to name each handset and then when you want to transfer a call or page a handset you can select the handset by name rather than number. Very useful as I could never remember which handset was located where. Also love the idea of being able to name a contact and then if the contact calls you the handset will announce who is calling by that name after the first set of ringtone. Expensive but worth every penny.

Bad points Nothing serious but you do need to be careful not to press the wrong buttons.

Excellent service from LiGo - ordered on Monday PM and arrived Wed AM. Customer service v.good - called them for advice and the person I spoke to was very helpful and knowledgeable. Price also seems good having compared this product on the web and in shops.
