I have been downloading charts for many years and have my own worldwide collection. However when I saw the discounted price on this at 18 Euros I decided to buy it as it seemed like a great interface for quickly accessing up to date charts. I must say it is really good. I use it on a laptop so I can get all the charts I need without pausing the sim. As it is cloud based many of the links are to the latest chart info. Was tempted by the iPad version but the Windows version is great and a great price to. Snap it up quickly before the price goes up again !!
