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.

Obsessed. Soothing, effective, fragrance-free, incredibly healing
Style: Tolerance Daily Foaming Facial Cleanser
I’ve been loving this so much I bought a second bottle after a few days of using it. It has all the skin soothing benefits of the tolerance lotion cleanser, but it’s also a really great cleanser. It’s almost not noticeable how good it is at cleansing because your skin doesn’t feel stripped after, but it takes things off really quickly. I was worried because it doesn’t foam a lot and it feels so nurturing — much like the tolerance lotion cleanser (which I use as a second cleanse when my skin needs a few days to recover from something like a derm office treatment) — but when I wash again with my favorite HG cleanser nothing extra comes off, and I tested it twice on waterproof eyeliner that I’d swiped on my forearm for an hour or so, the eyeliner dissolved and wiped off with two or three gentle swipes. It has a very emollient texture, so when you rub it against your skin it slips so easily you don’t realize it’s dissolving and taking things away because there is no friction. So it’s great at taking off makeup, it’s AMAZING at cleaning makeup brushes, and IT DOES NOT BURN MY EYES AT ALL. Also, it is FRAGRANCE-FREE… before I bought it I read a review complaining about smelling a citrus fragrance, that person either has some sort of brain tumor or something spilled on their bottle when it was in a warehouse because this is definitely a fragrance-free product. Prior to trying this, I had tried another cleanser that gave me weird acne hives all over my chest (never happened to me before) and I was struggling to heal the acne and the irritation. I noticed an immediate difference when I started using the tolerance cleanser on it; the fresh redness went away, the acne started healing, and the post-inflammatory hyperpigmentation has been healing fast. So I’ve been using this on my body as well and it’s soothing and moisturizing in all the places where other things have been drying. I have mild rosacea and I hadn’t realized how irritated my skin was from the last thing I’d tried until after 5 days or so of using this my skin tone looked much more even and the stubborn PIH I have from a two-zit hormonal breakout a month ago finally looked dramatically lighter (as recently as the week before, I’d needed to cover them with high-coverage concealer). Because this doesn’t foam much, some people might not realize how well it’s cleaning… I encourage you to judge it based on how your skin looks and feels. Since it is very emollient though, I do think it’s important to use it with a face wash scrubber or washcloth just to ensure you’re getting some mild mechanical exfoliation and clearing away skin cells that could be trapping stuff in your pores. For this reason, I do wash my face with this twice so the first wash can get off makeup/debris/oil and then the second wash can really penetrate and clean my skin.

No Scent and Gentle
Style: Tolerance Daily Foaming Facial Cleanser
I broke out in a case of Perioral Dermatitis recently and bought this product to help before I could see my doctor. Avene Tolerance facial cleanser has no scent and is very gentle on my skin. It didn’t burn when washing with this product, and even helped to slough off the dead skin around my lips. My face feels clean, not dry. I am still going to see my doc to get an RX for the inflammation, but I do believe this product helped to alleviate the dryness and tightness of my skin and lips. I’ve used other Avene products and I’m very happy with them. Even though these products are more expensive, to me they are well worth the money because they are much more gentle on the skin than any other products I’ve used. I will buy this product again just because of the fact that it’s so gentle. PS: at the time of purchase for this product, I also bought Avene’s Tolerance Control Skin Recovery Cream (you don’t need to use a lot of this one on your entire face), and Avene’s Cicalfate for lips. Between these 3 products, my lips and skin feel a lot better (however, I will still see my doctor because I have Crohn’s Disease and Perioral Dermatitis is considered an extra-intestinal side effect of Crohn’s).

Gentle everyday cleanser!
Style: Tolerance Daily Foaming Facial Cleanser
My go to nightly cleanser! Gentle yet effective. Removes makeup without leaving any residue behind. Also does not dry out my skin or cause breakouts! I would say it’s more of a cream cleanser though. It does not really foam up. It’s a decent size bottle for the price. The pump dispenser is an added plus!

So gentle and moisturizing. Great for super sensitive skin.
Style: Tolerance Daily Foaming Facial Cleanser
This is so gentle and moisturizing. Does not irritate my skin in any way. My skin is super sensitive and I have atopic dermatitis, it has been the best cleanser I’ve used to date. I was using another one from this brand and it was fine but this is the one I will continually stick with from now on. Just hope they don’t change the formula.
