The Keychron K3 Max QMK/VIA Low Profile Wireless Custom Mechanical Keyboard is an ultra-slim 75% compact mechanical keyboard designed for maximum versatility and efficiency. Supporting 2.4GHz, Bluetooth 5.1, and USB Type-C wired connectivity, it seamlessly adapts to various work and gaming environments. Users can take full control of their setup using the Keychron Launcher web app, which enables key remapping, macros, and custom commands with ease. The LSA (low-profile spherical-angled) keycaps are designed for both Windows and macOS, ensuring a smooth typing experience right out of the box.

Designed for fast-paced gaming and professional multitasking, the K3 Max features a 1000Hz polling rate in both 2.4GHz and wired modes, minimizing input lag for near-instant responsiveness. The Gateron Low Profile Red switches offer a linear, pre-lubed feel, delivering smooth keystrokes with low sound levels, making them ideal for office work and gaming. The keyboard’s hot-swappable version allows users to customize their typing experience without soldering, making it easier than ever to swap switches for a personalized feel.

Powered by QMK/VIA firmware, the K3 Max provides extensive customization options for power users. The ARM Cortex-M4 32-bit MCU with 256KB Flash ensures stable performance, while the IXPE acoustic foam dampens keystroke sounds, creating a quieter and more comfortable typing experience. Additionally, redesigned stabilizers help reduce key wobble, especially on larger keys like the space bar, Shift, Enter, and Backspace, ensuring greater accuracy and consistency. For Mac users, the dedicated macOS layout replicates the Apple keyboard function keys, making it a seamless transition for Apple enthusiasts.

Aesthetically, the K3 Max combines functionality with style, featuring double-shot PBT keycaps for enhanced oil resistance and durability. With 22 RGB backlight effects (plus a white backlight option), users can further fine-tune brightness, hue, and effect speed for a fully immersive experience. The 1550mAh battery provides up to 73 hours of wireless use with backlight off and 42 hours with RGB at its lowest brightness, ensuring long-lasting wireless performance. Compact, powerful, and highly customizable, the Keychron K3 Max sets a new benchmark for low-profile mechanical keyboards.

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough. It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy
