Purchased to replace an older Uniden product which had lasted us for many years. Positives include loud ring tone, built in Bluetooth to allow pairing with mobile phone, USB charger port, excellent operational range from base station. Being able to make/receive calls routed through my mobile from the handset is useful as I have limited mobile coverage and can leave my phone in the room with the best reception. Also if you use Android you can use the base station Bluetooth to trigger your phone to unlock. For me the only negative is that the Dial and End buttons are not opposite each other on the handset, but I am getting used to it.
