Review: Perfect Controller for Stepmania! - I play the exceptionally difficult levels in stepmania (16-18 footers) and I need a controller that can handle serious punishment! I have used many controllers and keyboards to play the game and have built strong preferences for what works for me (currently using dualshock ps4, and now this!) A few notes of feedback from my experience: - Very plug and play! Just go to the website, plug in the device and store the settings in the memory. - RGB lighting setup. I'm always nitpicky when it comes to lighting, but this controller passes the test! onboard lighting gives full rainbow wave with a few surprise goody functions in there too! -Solid build quality! This little controller looks and feels great with high finish screws and rubber grips to help prevent sliding -Key Switch Quality. Key switch quality is above average, I have felt more premium switches, but these are super-fast and very reliable which is what I really need! I am certainly a corner-case power user for this product and can tell you it is a godsend for my purposes!
Review: Good, adjust before for games. - Works as it should. There another review referring to a timing in the program which I would follow if you were to use this for games like helldivers.
