I have been experimenting with my new StroboPlus HD, and the build quality is great. When I registered the device, I was able to purchase the metronome at a substantial savings and it's worth adding the metronome feature. The sweeteners are a cool idea, although they may be more advanced than I need at this time. I would like to learn more about the programming and creating a personalized configuration. All said, I am very pleased with my purchase, and I would recommend it to any serious instrument player (guitar in my case).
