Review: 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.
Review: Questi cuscinetti a sfera sono perfetti per gli spinner. Dopo averne provati molti diversi, finalmente ho trovato quelli giusti. Non è semplice capire qual è l'azienda che li produce perché spesso non viene indicata (in Italia troviamo il nome dell'importatore che, però può rifornirsi da aziende diverse). Questi sono prodotti da Fushi Bearing.

These are smaller than the 608 bearings, a mistake I made at first. Until I realized how good these are, and adapters are easy to print for any 608 print piece that can't be altered. Now I use these for the main bearing in a fidget spinner, with cheaper 608 bearings for the external weights. Spins really good, is very quiet (not silent, but I didn't need silence), and is fairly priced for the quality. Definitely enjoying these and have already purchased more, with plans to continue doing so in the future.
