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: Great little keypad for Helldivers 2 Stratagems - Update: still love this little keypad. They actually release firmware updates via the web interface. I had a couple of small frustrations with the device (silly things like my lighting choice not functioning quite correctly, etc), which have been eliminated with these firmware updates Important note: for gaming, there was one adjustment I had to make in the web utility. Under the "Device Options" section, there is a setting called "Release Delay" which *should* be set to 1, unless you need the key to be held down for a short period after releasing the key. In my case, with Helldivers 2, having a setting higher than 1 is undesirable. I've attached a screenshot of the setting. Original review: Picked this up specifically for Helldivers 2. Out of the box, the device comes set up to function the same as your keyboard's up, down, left, and right keys. I use this thing to enter the Stratagem inputs, and it's worked fine for 3 or 4 dives so far. Also worth noting, this thing doesn't exactly have drivers that you install. Instead, you connect this device to your PC as you normally would, and then open a web browser (I use Chrome) and navigate to sayodevice dot com. The website will take a moment to initialize, but that's because it's actually detecting your device. Once the site loads, you can change each of the keys to be whatever you want them to be. You could make it W A S D or 1 2 3 4, you could even make it CTRL, Shift, Caps Lock, Tab, or L K Y V if you needed to for some reason. It actually shows you a standard full keyboard layout with a selection of "uncommon" keyboard keys listed below. You can also mess around with the illumination. I was rather surprised to find that the onboard lighting actually supports several different colors and lighting modes. It's a little tricky, I picked some lighting I liked but it seems to have wiped those settings when I disconnected the device from my PC (update: recent firmware updates have eliminated all of my lighting issues). The web driver thing also lets you update the onboard firmware, and change some settings I have no use for, such as identifying the device as a "joystick" or "absolute mouse" or "dial." Overall, for the price, I'm rather impressed. I've heard several people mention the drivers and the fact that they're in another language, but I've had no issue simply connecting the device and visiting sayodevice dot com. That's all you have to do. The website IS the driver. I didn't even have to mess with language settings on the site.
