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.

I’m A PT AND USING THEM IN MY CLINIC. PLS READ HONEST AND THOROUGH REVIEW.
Style: 15 Pound, Pair
I have been a PHYSICAL THERAPIST FOR 30 YEARS and I BOUGHT THESE FOR MY CLINIC. THESE WEIGHTS ARE COVERED IN A GRIPPING MATERIAL, NEOPRENE, MAKING IT COMFORTABLE and EASIER TO USE, ALLOWS YOU TO NOT LOSE YOUR GRIP, and IT IMPROVES THE SAFETY OF THE USER. I WILL BE BUYING THE 12&20 lb sets! THE VALUE FOR YOUR MONEY IS WONDERFUL!! AMAZON BASICS REALLY CAME THROUGH. It DID NOT INCLUDE AN INSTRUCTION GUIDE TO USE WEIGHTS SAFELY AND EFFECTIVELY. STELLAR FORM IS ALWAYS ESSENTIAL. MY WEIGHTS WENT UP TO 10 POUNDS, SO I DEFINITELY NEEDED ADDITIONAL WEIGHTS for those who can SAFELY TRANSITION . I MAINLY WORK AS A MANUAL THERAPIST …USING ONLY MY HANDS, AND MY BRAIN. TO DIAGNOSE AND TREAT ACCORDINGLY. (**ANYONE WHO HAS BEEN TO PT KNOWS THIS KIND OF ONE ON ONE TREATMENT IS UNHEARD OF**) I IMPLEMENTED MYOFASCIAL RELEASE, TRIGGER POINT THERAPY, DEEP TISSUE MASSAGE, AND APPROPRIATE STRETCHING AND EXERCISE . ONCE PATIENTS WERE ABLE, I INITIATED THERAPEUTIC EXERCISE. I WAS GETTING SO MANY REFERRALS THAT I MOVED FROM MY SMALL SPACE AND GOT A LARGER SPACE THAT LOOKS LIKE A TYPICAL PT CLINIC. I STILL EMPLOY ONE ON ONE TREATMENT, NO JUGGLING SEVERAL PATIENTS IN AN HOUR. I HAVE HIRED HELP TO ASSIST PATIENTS WITH EXERCISE AND STRETCHING. I PURCHASED TWO ADDITIONAL SETS ITHE SET IT I DID TO FIRST CHECK THEM OUT. I ADORE THESE AND HAVE SINCE ORDERED OTHER SETS. I LOVE TO WORKOUT AND I NEEDED TO USE THESE WEIGHTS MYSELF!! THERE ARE ALSO PATIENTS OF MINE WHO WILL PROGRESS TO THESE AS WELL. I AM SUPER IMPRESSED WITH THESE WEIGHTS AND CANNOT WAIT TO RECEIVE MY TWO OTHER SETS!! YOU WILL NOT BE DISAPPOINTED. EVEN IF YOU SWEAT, YOU ARE STILL ABLE TO HOLD ONTO THESE WEIGHTS COMFORTABLY AND SAFELY. SAFETY IS KEY, ALWAYS. I WAS EXTREMELY DELIGHTED THAT THEY ARE SOLD AS A SET BECAUSE MANY ARE SOLD SEPARATELY. THEY FIT PROPERLY ON A UNIVERSAL WEIGHT STAND, SO THEY ARE VERY EASY TO STORE. I CANT WAIT TO GET MY OTHER SETS! IT IS REALLY SAFE AND COMFORTABLE TO USE THESE WEIGHTS. THEY DID NOT GIVE OFF AN ODD ODOR, which is A HUGE PLUS because SOME OTHER BRANDS SMELL HEAVILY OF PLASTIC OR A CHEMICAL TYPE ODOR. THERE WAS NO ODOR AT ALL. THIS IS A HUGE PLUS. I AM COMFORTABLE SAYING THAT THESE WEIGHTS WILL LAST A LONG TIME BECAUSE OF HOW WELL THEY ARE MADE. YOU CANNOT BEAT THE PRICE EITHER!! THESE ARE ABSOLUTELY APPROPRIATE FOR PROFESSIONAL USE, AND, THEY ARE MEANT FOR PERSONAL USE AS WELL. SOMETIMES YOU JUST CANNOT GET TO THE GYM SO THIS IS WHERE THEY ARE KEY. HAND WEIGHTS HAVE THE ABILITY TO EXERCISE EACH MUSCLE OF THE TORSO AND ARMS. THERE ARE SOME EXCELLENT WEIGHT CHARTS OUT THERE TO SHOW YOU HOW TO DO THAT. IF YOU ARE GOING TO PHYSICAL THERAPY, THEN YOUR THERAPIST CAN INSTRUCT YOU AND KEEP YOU IN GOOD FORM. YOU COULD POSSIBLY HURT YOURSELF IF YOU WORKOUT INCORRECTLY. AS FAR AS THE LOWER EXTREMITIES, YOU CAN DO GROSS MOTOR EXERCISES BY HOLDING THESE WEIGHTS TO GET YOUR LEG MUSCLES BY DOING SQUATS, WALKING LUNGES, TOE RAISES, AND MORE. I DONT BELIEVE THAT MANY PEOPLE REALIZE JUST HOW MUCH YOU CAN DO FULL BODY EXERCISES WITH JUST TWO HAND WEIGHTS. IN CONCLUSION , THESE ARE EXCELLENT WEIGHTS THAT I WOULD RECOMMEND TO MY PATIENTS OR FRIENDS. THIS IS A HIGH QUALITY PRODUCT THAT WONT BREAK YOUR PIGGY BANK. I HIGHLY RECOMMEND VERY HIGHLY!. BUY WITHOUT RESERVATION!! A+++

Perfect size and weight with compact size
Style: Rack with 3 Pairs (3, 5, and 8 Pound)
I purchased the Amazon Basics Neoprene Dumbbell Hand Weights specifically for Pilates, and they’ve been a great addition to my routine. The size and weight are perfect for controlled movements, helping with muscle toning without feeling too bulky or awkward. The neoprene coating gives them a comfortable, non-slip grip, which is especially important during longer sessions or when your hands get a little sweaty. They feel secure and easy to hold through a full workout. I also like the shape—they don’t roll around on the floor, which makes transitions between exercises smoother and less frustrating. They’re compact enough to store easily but still feel durable and well-made. Overall, these are a simple, affordable, and effective option for Pilates or light strength training. I’d definitely recommend them for anyone looking to add a little resistance to their workouts without overcomplicating things.

Good purchase
Style: 3 Pound, Pair
These are just the right weight for me to start gaining muscle back in my arms, after a large weight loss. They are of good quality, they are covered in a nice rubber like coating that is soft to the touch. They are small enough that i can take them with me when I travel. My dog has got hold of them a couple times and played with them, and they held up just fine without any damage.

Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for. The Pros: • That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic. • The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work. • Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done. • No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box. The Cons: • Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around. • Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily. The Verdict: If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!
