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.

Good for ebike tires
Size: 1 Gallon + Tool, Set name: Small Tire/Bicycle Formula
Got it for my son’s older ebike that my wife rides now. He kept on popping tubes, maybe because of his weight. Anyhow, I fixed it up for my wife and put some FlatOut in it to prevent flats. Seems to work so far. Got the off road FlatOut for my ebike’s fat tires. Easy to add to the tires. The pump clogs up but it’s easy to clean. I will always add this to all tires moving forward!

Cool stuff
Bought a Swisher rough cut mower to pull behind the Yamaha Rhino to cut our 6 acre field. We were cutting down 8 foot trees, no problem, but one tree had big thorns on it and destroyed the rear tires of the Rhino. Replaced all tires, and since we still have to mow the field I opted for adding this to the tires. Very easy to use, and now I have the confidence that if we get a puncture we will still have air. Also bought their flat fix kit that comes with CO2 cartridges. Brilliant space saving idea! So, haven't had to test this stuff yet, but I'm fairly confident it will work. An added bonus is that it can clean up with water. I've heard stories of tire places not wanting to touch a tire with the other brand that comes in an aerosol can, as it's dangerous and messy. Time will hopefully not tell. It's like insurance - hate to pay for it until you need it, but hope you never do.

Got me home after a sidewall cut!
I am very happy I bought this tire repair kit earlier this year. I was out riding my UTV today and had a flat tire caused by a sidewall cut. I used the tireject kit and was up and running again pretty quickly and it was more than enough to get me back the the truck and trailer. I bought this kit instead of going with a spare tire. I have already bought more of the fluid to replace what I used today.

Amazing sealant and easy to use even in cold weather.
This product is amazing. It poured right into my tire even though it was -8 celcius. It sealed the crack in my aluminum rim and the the leaky tire bead after I hit a rock. Sealed everything and got me back to trailer and it is still holding air.
