I think the ShadowCast itself works beautifully. Easy setup, good quality, great price. However, I'm running into some issues, along with many others, with the Genki Arcade app. Since the app or web browser equivalent is required to make the device work, I was really hoping I wouldn't have as many issues as I am. Basically, whenever you power cycle your computer in any way, the app opens, then almost immediately shuts down without input. I had to uninstall and reinstall the app twice within a week. If you buy the ShadowCast, USE THE WEB BROWSER EQUIVALENT.
