Fidget Spinner Replacement Set: R188 hybrid ceramic bearing, stainless steel caps (7/8" diameter), bearing removal tool. Fits most spinners w/ R188s & 7/8" caps or larger. Fast prime shipping.

100% satisfied with the purchase. I replaced the caps and bearing on the I love fidget stubby with this set, that just happens to come on the GEEZ hand spinner. Now, just a little research and you'll find all these different company names are what seems to me to be the same company, marketing at its finest. That being said, this set has a fair price, the caps are spot on, the bearing works great, and we can always use the extra tool. A good deal in my book.

The button was way too big for my R188 spinner so I will probably not use it (I should have paid more attention to the dimensions). But worse, the bearing was very rough and noisy for a hybrid ceramic one. So, I was fairly disappointed with this set.

I ordered this to replace the crap button on the ilovefidget tri-bar such an improvement I can now balance the spinner on my knife. The guy the first review doesn't know what he's talking about spinnerhub "Geez" uses r188 ceramic hybrid, and spinnerpro "Polaris" uses a 688 ceramic hybrid so if you have a ilovefidget spinner this is the cap you want to swap it with

They feel great but they stand off the bearing a bit too much. Maybe if they cut .5mm on each piece the fit would be better.

I bought this primarily for the replacement tool. I like the key effect to loosen the bearing retention rings, no sliding around. The bearing and buttons are good as well.
