I bought this for my church. I have a philips in my own office. Battery life is very close to advertised. The shipment arrived complete and undamaged. I really like the new Child Key, which is reusable, rather than buying a second set of pads. Especially since the pads expire in a little over 2 years and need replaced. This is because the adhesive gel can harden and not stick when you really need it to! A great kit with the accessories you want to have should the need arise.
