SayoDevice O3C OSU Keyboard Rapid Trigger Hall Switches Magnetic Linear Switches Keyboard with Knob and Screen,Copy Paste,Shotcut,Macro Hotswap Mini Keypad.…

Amazing 8000 hz polling rate the reactivity is amazing especially for games like geometry dash/Osu it functions very well and has a volume knob very useful if you have a smaller keyboard without normal sound function keys, its easy to connect and was pretty comparable off the start.

I almost gave this product only 4 stars because in the world of Amazon, this item ships SLOW. Just be prepared for that. As far as actual quality - worth the wait. Exactly what my son was looking for. He now uses it daily. Functions exactly as it should and has enhanced his game play.

12 year old was able to program on his own and is thrilled with performance of this Sayo. He uses it for Geometry Dash game. You can use it with an iPad or laptop. Great tutorial by a British young man who teaches how to program it for iPad usage.

Little hard to work but overall great looks and feels amazing and works well

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.

The product feels high quality. The switches are really good and responsive. If you buy this product make sure you callibrate it with the inbuilt callibration tools.

Performs better than expected for the price, customization is easy through their website. A must have for any OSU or GD players

My son asked for this for Christmas, I don’t know what is for, but he is very happy with it so that’s a good review for me, lol. Is a small device, color is nice and he says that makes his game more efficient

osu!プレイヤーであれば絶対買うべきです。 通常のキーボードでも良いですが、手元配信する際にばえる為使用しています。 キャリブレーションも簡単で、更新自体もすぐに出来ますしマッピングも楽でした。

Perfect, brought for my son who is addicted to geomatry dash and is on the extreme demon levels. He cannot believe what a difference this makes.. he struggled with the mouse but has got much further using this. Love the light up colour aswell.

Excellent 👌

Me encanta, es tal cuál se ve en las fotos y como se explica en la descripción. El tacto de las teclas es super suave.
