Got this for my kiddo who plays geometry dash and honestly I'm geeking out on this way harder than he even is. It's so incredible all the different functions it has I haven't even figured it all out yet but this was definitely a solid purchase. It looks and feels really nice too. The size is perfect and there is zero lag. As far as I'm aware it doesn't connect with Bluetooth, as it shouldn't sense Bluetooth is not the kind of thing you want to use if you want to skirt lag. Definitely make sure you have a proper cable though, I do not believe for a half a second that the cable this thing comes with is proper. Make sure you get at least a 5 gig data cable USB-C

The media could not be loaded. Extremely satisfying to use. Even when I am not playing geometry dash with it, I use it. I have the dial set to volume up/down and escape. I have even set customized profiles for different applications and set different RGB profiles with them so I can differentiate keybinds with ease. I haven't done this, but you can even set multiple keys to activate at once, all in one keypress. Could be helpful for frequently used shortcuts.COOL NOTE: If you have a tempered glass side panel on your PC, ensure it is clean, along with the bottom of your sayo (the silicone feet pads), and stick it to the glass (literally zero adhesive, only the feet pads). This is so satisfying and holds up really REALLY well. No joke, when I remove it from the glass, it sometimes pulls the PC with it. This is how I have stored my sayo when not in use. It has stayed up for literal months with zero problem. In this configuration, I have a volume knob on the side of my PC case which I use ALL THE TIME. NGL, I think I would have gotten it just for the volume function.

My 16yr old loves it. He’s pretty rough on things and this has strong, great quality for the price. It’s comfortable for him to use and the perfect size and weight to fit on his desk. There’s also options to change the keys on there, so that’s cool. The keypad is good and spaced normal. It works great because he hasn’t complained about anything lol. It has a USB-C cord to hook up to the computer, I guess. No bluetooth.

The media could not be loaded. The keypad is pretty good, nice construction, but very loud. If you do use it on a bare table even with iems its obnoxiously loud. It's preferable to use a deskmat or mouse pad to deaden the sound. There is no guide that comes in the box of how to setup rapid trigger.Rapid Trigger Guide:Hold down the volume Knob, Go to Button>Key stroke>spin knob to select a keyTrigger: 1.50mm (Actuation point)Release: 1.40mm (Reset point)^Normal key acutuation point, when your key press travels 1.50mm Rapid trigger start. recommend setting to your mechanical keyboard acutuation point or slightly less between 1 to 2mm.RT Top: 0.65mm (Rapid Trigger Top Border)RT End: 3.95mm (Rapid Trigger Bottom Border)^ Zone in which rapid trigger works, If you go above the RT Top when you let go of the key you have to press 1.50mm to trigger Rapid Trigger.RT Trigger: 0.25mm (Rapid Trigger Trigger Sensitivity)RT Release: 0.25mm (Rapid Trigger Reset Sensitivity)^ It dictates how much your key needs to travel for Rapid Trigger to send a press, so 0.25mm (RT Trigger) of travel to have an input and 0.25mm (RT Release) to reset within the Rapid trigger zone*Osu subreddit has a guide on Rapid Trigger, you can check that out if mine doesn't make any senseKeybinds:Sayodevice.com/keyClick “search sayodevice”, pair your device. Select a key, click “general key”, find keybind, press ok and press submit.How to sound deaden in a jank way, buy a 2mm thick sheet of silcone with tape on it. Cut a piece the shape of the empty space on the bottom of the keypad and stick it on. Cut another piece the shape of the keypad. Take the plastic film off the silcone and stick it on the silcone in a corragated cardboard pattern, it needs those bubbles to sound deaden. Use some tape and tape it to the bottom of the keypad. Now it’s half as loud.

For all the osu! and Geometry Dash grinders out there, welcome. You didn’t want to shell out $200+ for an 8000Hz keyboard, nor did you want to keep abusing that poor, half-broken mouse. So here you are, staring at this device—This... SayoDevice, flipping between this tab and that video review you’ve been studying like a final exam.Let’s get straight to it—does it work? Yes.Rapid Trigger? Check.8000Hz polling rate? Check.Incredibly fragile? Oh, absolutely.Now, with that last point in mind, onto the fun part—flaws.Issue #1: This thing has the durability of a wet paper bag. If it doesn’t break on you in some way, congratulations, you either got lucky or you’re handling it with silk gloves. It’s not a $250 keyboard, after all.Issue #2: The screen. Oh, the screen. Out of the box, it just… stays on. The RGB turns off, but that backlight? Nah, it’s pulling an all-nighter whether your PC is on or not. And unless you’re deep in Reddit lore, you won’t even know how to fix it. That alone stole the fifth star off this review and left it for dead.But let’s be real—if you’re here, you already know what this thing does. You didn’t just stumble onto this listing by accident. So sure, maybe you could save a few bucks ordering from that other site, but is skipping a Chili’s Triple Dipper really worth dealing with slow shipping and a nightmare return policy? Didn’t think so.
