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.

My new edger
Style: 9" 2T Cutting Blade
I love this edger, I attached it to a Kobalt 24V trimmer with detachable head. It took me a minute to remember how to use an edger with a steel blade after I have been using a string edger for the last five years. The weight is liter than the battery/motor pack. The design and functionality is amazing, I love the adjustability of the depth control system. This thing is super easy to use, loosened one bolt, slide on the attachment align the silver push button and tighten the one bolt by hand and go to work. The durability is yet to be determined, it well made. I like that the right side is open faced which means less chance of clogging up the blade. I am very happy with this purchase and I believe it is a great value for the money

Made it through the first season
Style: 9" 2T Cutting Blade
Product value compared to name brands not to bad so for. Not sure I'd use it for contract work, but great for homeowner use. Engine seems to have an odd burning smell, but performs good (yes I have the correct oil/gas mix ratio which is 50:1). This is very similar to the Stihl models, aluminum shaft tubing on the attachments appear to be slightly thinner than Stihl, but they perform fine. So far it's been a great value for all the attachments you get in the kit. Definitely like the angle capability of the hedge trimmer and ease of changing out the attachments. Chain saw blade did dull fairly quick, but expected that based on it's size. Jury still out on longevity.

Edger Does Not Fit The 52CC Trimmer
Style: 9" 2T Cutting Blade
Might be a great cutter head?? I purchased the 52cc trimmer and edger as a package, however the edger does not fit the trimmer??? Therefore, it is useless... Will see if it fits my 25cc trimmer and maybe change the review... They should tell people in the description that their edger will not work with the 52cc trimmer....

Cut edges like a pro
Style: 9" 2T Cutting Blade
Better, much better than the OEM yellow and black brand. This has an all metal guard and the blade does not bind when it comes into contact with concrete. I have used it all summer for edging two commercial properties and my own lawn, it’s still turning and cutting with ease. Being all metal adds weight but the trade off over fragile plastic is worth the durability.
