娘にくじ引きで当たったAppleWatchを上げたらこの商品をプレゼントしてくれました。 そんなことは皆さんに関係ないのですがアクションカメラで撮影した動画をYoutubeへアップするという新しい趣味に大活躍です。 このカードを使って撮影した動画のタイトルはこちら。是非Youtubeでお楽しみください。 【現地映像】King Gnu CEN+RAL Tour 2026 Tokyo Day2

PCでは問題なく使えましたが、iPhoneでは認識しなかったので一応書いておきます。

タブレットの外部メモリとして使用していますが期待していた以上にスピードがあり値段を考えるとよい買い物でした。

車のドラレコ用に買いました。携帯に接続して画像確認に良いです。

デザイン、丈夫で使いやすさは良い。 他のカードリーダーと一緒で独自ソフトドライバーで認識、消費電流が大きいのでスマホ接続は短めになる。

Ok

Chegou em otimas condições, não tive como testar muito mas consegui saber que funciona.

Fast micro sd card. Uses for video surveyance.

Been using it for 2 months now, have not faced any issue, looks good, nice quality, have not faced any data loss, supports most android phones that can support high memory.

This is a fairly (and surprisingly) decent Micro SD/uSD card reader from Amazon Basics that's reasonably well-made and for the most part works as expected without issues. It's reasonably small and compact although far from the slimmest that I've come across and tested due to its odd and slanted shape that's just weird. It has a typical plastic shell that's certainly not something to write home about; however, it does have a spring-loaded card slot, which is a surprise to me (and indeed a pleasant one at that). As for its dimension, it's about 25 mm in length at the shortest side and 29 mm at the longest. As for width, it's about 18 mm at the shortest and 23 mm at the widest. Finally, the thickness is about 11 mm; however, the slanted side has a length of 12 mm measured at the surface. As far as data transmission is concerned, it's able to provide the [nearly] max speed supported by the various Micro SD cards that I've tested and the best result is about 175.25 MB/s for read and 155.85 MB/s for write, which is again fairly good. This particular card reader also supports OTG that many others don't, so that's certainly a point in its favor. Before purchasing this, I tried about half a dozen UHS-I card readers from various well-known brands including Kingston, UGREEN, and TP-Link etc. just to name a few. However, most of them weren't able to achieve speeds faster than 104 MB/s (which is the max speed for UHS-I), and for the few that could go beyond 104 MB/s, they were capped at roughly 150 MB/s, which was weird. The max speed for UHS-I is 104 MB/s and that limit is increased to 156 MB/s (full-duplex) or 312 MB/s (half-duplex) for UHS-II; however that requires the use of an additional row of connectors on the cards as well as the card readers that relatively few have adopted even today. ★ In the meantime, proprietary technologies have been developed by SanDisk and others to bump up the existing 104 MB/s limit to something much higher, including DDR200 (170 MB/s) and DDR225 (200 MB/s) and so on. This is the ONLY card reader that I've tested in the last month that's actually able to achieve 175.25 MB/s (max 180 MB/s for the card in question) via UHS-I interface. Kingston used to have one that actually worked (from about 3+ yrs) but that's no longer the case with the new version that's available at the moment, so if you need a UHS-I card reader that actually works to go beyond 104 MB/s at the moment, this is THE card to get. ≡ Value All things considered, this is a fairly decent uSD/Micro SD card reader that's fairly small/compact and works as expected without issues. It's the ONLY UHS-I card reader (out of the half a dozen or so cards tried) that's able to go beyond 104 MB/s (max 200 MB/s claimed) imposed by the standard. I just wish that it has a slimmer and rectangular shell instead of one that's oval and slanted at the rear, which is just odd and weird. It's reasonably priced at $10 for what it provides and its overall build quality, features (i.e. DDR225, 200 MB/s), usability, versatility, and performance.
