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 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.

Everything fits perfectly and installs just like the original parts
Color: Saros 10R/Qrevo CurvX Accessories Kit
it exceeded my expectations. If you own one of these models, this kit is a smart and cost-effective way to keep your vacuum running at peak performance. The value is excellent. Everything fits perfectly and installs just like the original parts. I didn’t notice any compatibility issues, and the vacuum recognized and performed with the parts flawlessly. The main brushes are sturdy and pick up debris efficiently, while the side brushes sweep edges and corners just as effectively as the OEM versions. The HEPA filters do a great job capturing fine dust, which is especially noticeable if you’re sensitive to allergens. The mop pads are absorbent and hold up well after multiple washes. I also appreciate having extra dust bags on hand. it makes routine maintenance simple and stress-free. The included cleaning tool is a thoughtful addition that helps remove hair buildup quickly. Overall, this kit delivers quality, quantity, and convenience in one package. It’s an excellent investment for maintaining your Roborock and extending its lifespan. Highly recommend!

Fit My Roborock Saros 10R Perfectly
Color: Saros 10R/Qrevo CurvX Accessories Kit
I got a Roborock Saros 10R for Christmas and purchased this accessory kit to have on hand when they are needed. I have an older model Roborock and you never know when something might need to be replaced. Since the accessories for my older Roborock do not fit my new 10R I wanted to ensure that I have dust bags on hand and don’t lose precious vacuum time waiting for delivery. After shopping around I decided that this set, for the price, made the most sense for me. Not only do I get the dust bags, but I also get replacement mop pads, main brushes, side bushes, filters and tools so when it’s time to replace those items, I’m ready. Although I don’t have a need to replace all of the parts just yet, I did check each of them to make sure that they fit and that the quality appears to be adequate. Everything fit well, and looks to be a reasonable replacement. There was some slight quality differences, however, there’s nothing that is concerning, and the quality difference is so slight that it’s barely noticeable. Considering the price difference from the name brand this accessory set is an excellent bargain!

Does not have everything shown
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
This kit does not have all the items shown. There are only 4 bags, not 6 as shown. There is only 1 red and 1 black roller, not 2 as shown. There is a screwdriver included but no directions. There is no odor to it and the items look durable but I have no idea how to replace the rollers and spinny things since there are no instructions. The bags fit my robot vacuum ok and are durable. There needs to be directions included as well as everything shown. Otherwise, you aren't getting your money's worth.

Solid Kit That Saves You Some Money
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I ordered this accessories kit for my Roborock Saros 10R mostly because I didn’t feel like spending a ton just to keep up with teh normal maintenance. After using it for a bit, I can say it’s been doing exactly what I hoped it would. First thing you notice is the cost of course, keeping these robot vacuums running can add up fast, and this kit really helps take the sting out of replacing the usual wear parts. Most of the pieces line up with the Saros 10R really well. Everything went in without a fight and once installed, it all works the way it should. Brushes rotate fine, filters sit where they’re supposed to, and nothing feels janky or poorly sized. Quality wise, it’s pretty close to the name brand stuff. You can tell there’s a small difference if you really look for it on some parts. Some of the plastic feels a bit lighter and a couple items don’t have that same premium feel. But in use, I’m not seeing much of a difference, cleaning performance is still strong and the vacuum hasn’t skipped a beat. Durability is the one thing you can’t fully judge right away. So far though, everything seems to be holding up nicely. No fraying, cracking, or early wear, so I’m cautiously optimistic they’ll last about as long as the originls. Overall, this kit is a good deal for the money. It does what it’s suposed to, saves you some cash, and keeps the Saros 10R running smoothly. Not perfect, but definitely worth it. Four stars.

most can fit saros 10, but not all
Color: Saros 10R/Qrevo CurvX Accessories Kit, Color: Saros 10R/Qrevo CurvX Accessories Kit
I should have done a little more research with these. I purchased this for a Saros 10, i thought the Saros 10 and 10R was basically the same besides the filters. I was wrong. Although the brushes are the same size, they didnt fit. They lacked a special metal piece on one side, and the 10R has a different shape on the other, cant even jerry rig it to fit. The filters didnt fit my Saros 10, but that didnt cause the dropped rating, but they quality of it looks very good, and seems well made. The side brushes are good and they fit my Saros 10, replaced them and didnt have a problem. The bags also fit and they are very good. The mopping brushes did not fit, but it was very well made and definitely wasnt just a cheap set. The brush and screw driver were just to add additional number counts and basically useless.
