My only complaint so far is that towns and features do not seem to be searchable. In fact to include an existing small town as a waypoint you actually have to create a new user waypoint at the town then put it in to the flight plan.
I used to gripe about this too. Then I realised that in Map Mode you can zoom in and spot the points that it does have, read and write down the code, and then use that code in the quite separate FPL mode. Towns often have helipads, etc. Kludgy, but usable.
I am impressed at what it has, eg LMS (as in egLM Sierra) for White Waltham Point Sierra, which isn't even on the CAA charts.
One caveat: my database is bang up to date. A friend's 6 month old database doesn't have all the codes I have.
