I purchased direct guitar 3.0 for Mac, running Kontakt 5. Initially I had a problem with the download, but Andreas very quickly sorted the problem with the suggestion of a fast downloader. He was extremely helpful and I'm delighted with the product. I'm surprised that not more people have heard of this product. A rival company took 30 hours to sort a similar problem and in the end I gave up and got my money back. Mac's seem to struggle with .rar folders.
Andeas even offered me a DVD at no cost. Excellent after sales care.
