Easy installation. Display clear menus and easy to access. Simple to learn and use. Management of the various menus easy. Simple to implement records. In short very good product that gives me satisfaction. Delivery and parcels on top as usual. I had to return this August 10 due to a block I do not know the cause. Obviously the exchange was immediate and pro. The problems are solved definitively and no blockage to date. After-sales service is particularly effective.
