If you're expecting a perfect module, you shouldn't consider buying it. There are still many more or less important bugs. But after all, it's still "early access" even if that is already for a long time. If you can live with those bugs and just want to fly around with the Harrier, without every system working accurately, it's a lot of fun. VTOL alone already is fun. I personally don't regret that I have bought it. But most of the time I'm flying the A-10C and the Harrier is a welcome alternative. What other VTOL alternative do we have? I suppose the F-35B won't be available in DCS during the next few decades, so there's not much of an alternative if you want to try a VTOL airplane.
