My husband is very pleased with them. It used to have 2 easy 2 use and very clear buttons for Camera and Video. They are really a great buy for the price. I downloaded the app for these key finder and it works then it stops working the next day. This unit operates on the 2. , it seems fine. Por otro lado, el equipo funciona perfectamente, como era de esperar de un producto de Plantronics. Fully charged. I’m sure that she will love it. Came quickly and packaged nicely.
