I highly recommend them 5 stars!
Number of Items: 10
I purchased these R188 bearings for my fidget spinner project, and I couldn't be happier with the results. The bearings spin incredibly smoothly right out of the package and provide impressively long spin times. Once installed, my spinner felt much more balanced and effortless, with very little resistance. The nylon cage design seems to help maintain a consistent, quiet operation, and the bearings stay smooth even after extended use. They roll freely with no grinding or rough spots, making them perfect for anyone looking to upgrade their spinner's performance. Another big plus is the value. Getting 10 high-quality bearings in one pack is a great deal, especially if you have multiple spinners or like to keep spares on hand. Pros: Very smooth and consistent movement Long spin times Quiet operation Great quality for the price Convenient 10-pack Overall, these bearings exceeded my expectations. If you're looking for reliable R188 bearings that deliver smooth performance and extended spin times.

Best purchase ever! Put them in all my spinners
Number of Items: 10
Ordered these after seeing someone mention them in a review somewhere else on a fidget spinner- they were discontinued but these weren’t, so i decided to order. BEST DECISION EVER. OMG. QUALITY. my jaw dropped when i spinned for the first time after replacing with these. I couldn’t believe how smooth, quiet and amazing the spin felt. And they can go for a looooong time. It felt like seeing the light of day when you never knew what it looked like. Lol but seriously. The quality for the price is soooo good. Like these are exceptional. Even feel so much more well made then the cheap ones that come in the spinners. I will definitely be buying these again and putting them in all my spinners. They work so good. Perfect fit also. Packaging is nice, resealable sturdy bag. Came fast shipping as well. Two thumbs up 👍 Would give it 10 stars if i could.

Replaces DYNAAGE Fidget Bearings
Number of Items: 10
These fit perfectly as a replacement for the ball bearings in my DYNAAGE Fidget. I think they may be the same ones that were used originally. They are quiet and effective. At a dollar per bearing they are pricey but you can probably find these elsewhere at bulk prices. Thanks to the seller for making the dimensions so confusing. 1/4"x 1/2" x 3/16" is indeed the correct measurement. They are NOT 1/4mmx1/2mmx3/16mm.

Wow! Bang for your buck 💥💵
Number of Items: 10
As someone who’s tried my fair share of bearings, let me just say—WOW. These bearings have truly set a new standard for performance and quality. From the moment I popped them into my spinner, I knew I was in for something special. Smoothness: The spin is absolutely flawless. It feels like a well-oiled machine (pun intended). Whether I’m casually spinning to de-stress or pushing the limits of my tricks, these bearings hold up effortlessly. No wobble, no noise, just pure, uninterrupted motion. Durability: I’ve been using them for hours on end, and they still perform like they’re fresh out of the box. The build quality is clearly top-notch. I can already tell these are going to last me a long time. Value: At this price point, you’re getting premium performance without breaking the bank. I’ve spent twice as much on bearings that didn’t even come close to what these deliver. If you’re on the fence, let me save you some time: Buy them. You won’t regret it. Whether you’re a casual spinner or a die-hard enthusiast, these bearings will elevate your experience to a whole new level.

Longest spin per dollar choice
Number of Items: 10
Out of everything else available on this website these are the second best I have found for R188 spinner bearings. But they do have shorter spin times to the Freelove replacements. They do see to be high quality, and fit nicely. These bearing are the best choice when it comes to value.
