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 2.4 GHz, 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 Brown switches offer a tactical, pre-lubed feel, delivering responsive keystrokes with medium sound levels, making them ideal for Midway 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.

Transformed my feet
Flavor Name: XL silicone socks 2 pairs
After trying several other brands that actually my size did not have the luxury feeling of these. T although x large they have the BEST feel and function. I put lotion on then slip them on and within a few minutes my dry cracked heals are soft. Really a nice product.

Tight at first, but they stretch after a short time...feel perfect after the first week!
Size: 9.5-10.5, Color: Charcoal Faux Fur
I love them! My first impression was "oooh, this is too tight". I wear a size 10 shoe and honestly, the 9.5-10.5 felt tight when I first tried it. Without socks it felt okay, with socks my toes were right at the top. But I loved the style so much I decided to give it a chance - I am SO glad I did!!! They do stretch and give, so don't expect it to be tight forever. I have had them a week or so, wearing each day (I WFH) and they feel really nice. I also live in the mountains, we just had our first winter storm, and these slippers are nice and toasty. Exactly what I needed. The memory foam is plush, though I have had other slippers with it and I know it will squash down over time. Right now, it is a nice feeling as I walk around the house. They are super cute looking, wearing leggings allows me to feel like I am stylish even while still wearing my sleep thermals. YAY!

favorite slipper ever
Size: 8-9, Color: Charcoal Faux Fur
I love these slippers. They look great with pants tucked in. Incredibly warm and comfortable. I wear them almost every day. Fit is true to size. They stay up but are not tight at all. On top of that I get compliments on them. Highly recommend.

Favorite Slippers Of All Time
Size: 6.5-7.5, Color: Charcoal Faux Fur
ETA 7/2024: So I ended up buying a size 5-6. They fit better around the top and sides of my foot but the sole is a bit small. The 6.5-7.5 sole fits better but the material around the top and sides is roomy so it bunches up. Sigh. I still love these slippers but the fit is frustrating. I'm obsessed with these slipper boots! They are so cute and comfy. They look especially good with leggings but I also like that I can tuck other types of pajama pants into them. I'm short and have to fold the waist of most pajama pants so they're not super long on me, but with these boot slippers on I don't have to worry about my pant bottoms dragging on the floor since I can just tuck them in. I like that they have rubber soles. I love the look of the faux fur but not sure how easy they will be to wash because of it. I wear a 7 or 7.5 and I got the 6.5-7.5 size. Even with thick socks on they are roomy. Because they are house shoes it doesn't matter much but I probably could've sized down. I like the way they look so much I might buy a size down and use that pair for wearing outside of my house. Some other reviews said they have a strong smell but mine did not.
