Works Pretty Well (Read & Write Speeds Below)
Works Well but The only Problem i would say with this usb is that it does get hot.

Great!
Incredibly good value and reads quite fast for the price! Also writes in bursts at a decent speed. If you're not writing large files, it's a no brainer. Otherwise, at USB 3.0 speeds it gets quite warm after some time and I'm guessing the plastic build doesn't dissipate heat much. If you plan to write constantly, I would recommend looking at the metal Luxe version which should retain its speeds longer.

Tiny but mighty
This thing is minuscule but certainly packs a punch. No issues plugging in and using, and file transfer through a MacBook Air’s USB-C 4.0 was BLAZING fast (or at least yards faster than I’m used to from my 10-year-old Intel Pentium PC).

記載通りの性能で欠点も特になく大満足
10年ぶりくらいにUSBメモリを買いました。自炊した漫画や動画を格納してiPhoneで開くのに、本体やクラウドストレージを大容量データで圧迫させたくなかったのが目的です。 以前買ったときはシリコンパワーのUSB3.0 16GBで3000円くらいでしたが、今は1000円ちょっとでUSB3.1 64GBが買えるとはありがたいです。SanDisk製のフラッシュメモリなので信頼性も高そうです。 iPhone 16ProにType-C側をぶっ刺して使ってますが、表記通り実測値でも読み150MB/s・書き100MB/s程度の速度が出てます。他のレビューにもあるとおり小さすぎて無くしそうですが、キーホルダー等に取り外しできるプラバックルで付けておくと良い感じです。Type-A側を使ってないのと落下等の衝撃はまだ未経験なので耐久性は不明です。 総評としては非常に満足しています。あまりUSBメモリを買うことはないですが、今回も当たりの商品を購入できたと思います。

Works fine, delivery fast!
Very handy having both a usb and type c port. Has a short installation app for phones but great for that easy access when it has two ports to plug and play. Very compact! So small in fact that I have to clip it with a keychain so it doesn't disappear on me, but that's a compliment!

Good as advertised.
Works as intended. Pretty straight forward no need to reformat. Transfered my files from my old macbook to my samsung fone. Fast transfer too. Transfered 30G files and it was quick. Legit product.

Buena solución para entradas tipo C!
Es buena! Aún que el sistema ocupa 5.28gb de información, funcional y restante nos deja con 123 gb! Es compacta y pequeña trae para poner un cordón y es tipo C y USB normal, es una gran solución para los que compramos la MacBook neo
