Not a genuine product!!

Reviewed in Australia on 5 December 2018

Capacity: 200GBStyle: Ultra 100Verified Purchase

The product is a fake. Used it for my switch for a month and data got corrupted everytime it hits 30gb. I had to go out and buy another sd card from a geniue retailer. The difference was obvious. Highly do not recommend this!

256GB Not Genuine

Reviewed in Australia on 24 November 2018

Capacity: 256GBStyle: Ultra 100Verified Purchase

I am unsure about the other varieties, but I can confirm that the 256GB version is not genuine and from my testing has less than 50GB of actual space. Steer clear of the 256GB version in particular. Have bought the 400GB version and will update this review once it arrives.

FAKE!!! THESE ONLY HAVE 32GB.

Reviewed in Australia on 21 November 2018

Capacity: 128GBStyle: Ultra 100Verified Purchase

Using h2testw and can confirm that these are fake. You can already tell from the packaging and the card itself but I gave it a chance and only 32GB was OK, the rest was corrupt. Surprising as many only give you 8GB but still a terrible deal. Very unhappy and definitely will be returning this product.

128gb is genuine, fast data transfer.

Reviewed in Australia on 29 May 2019

Capacity: 128GBStyle: Ultra 100Verified Purchase

** Australian Amazon review **
I bought this having already read the feedback from Amazon.com, which questioned the authenticity of the product. Those were other sellers though, Amazon Australia sells this one direct.
I am fairly certain that this product is genuine, and I have used h2testw.exe to test the size to make sure it's accurate. I definitely got 128gb, and the read/write speeds were close enough. It inserts nicely into my galaxy s9 and copies data relatively quickly. You also get a microSD to SD adaptor which is handy.
Happy with it so far.

400GB works great for Nintendo Switch

Reviewed in Australia on 12 July 2018

Capacity: 128GBStyle: Ultra 100Verified Purchase

Got this to expand storage on my Nintendo Switch and so far so good. Great speed and reliability, which is what you expect from SanDisk. Comes with normal size SD adapter if you need to transfer files to a Mac/computer.

UPDATE 21/6/19: I had initially purchased the 128GB version of this card for my Nintendo Switch, but having run out of space for games I decided to give this one a go at 400GB. It works flawlessly as the previous card did, so now I have a lot more room for games. The price of the card has come down, so the 400GB is the best value per GB.

Best bang-for-buck, good seller.

Reviewed in Australia on 1 November 2018

Capacity: 200GBStyle: Ultra 100Verified Purchase

First, before we discuss the seller, Amazon, I take issue with what you posted on the site. Namely: "Delivered today
Package was handed to resident".

I was not aware that sticking the envelope containing my MicroSD card and its adapter into my mailbox was the same thing as physically handing me the parcel. Please be honest in future. There is a good Amazon.

Having said that, I ordered this item from Shopping Square Australia, and they exceeded Amazon's estimates of when the item would arrive, and then some. The estimate was 5 - 12 November, and I have it on the first. So Shopping Square Australia, give yourselves a pat on the back for being prompt. Thank you.

The card itself seems to work fine. I am in the midst of converting all of the songs from my now-pooed-the-bed iPod Classic to FLAC so I can play them on my NW-A55 and whilst the USB connection to the player is only USB 2.0, so far the card has taken somewhere around 64 gigabytes of my music without a protest. It will be interesting to see when I finish transferring all of the 140+ gigabytes of music from the Classic onto this card, but also when I start buying some of the 96 kHz music that I have been wanting to buy and play for a while now.

Long story short, if you need a MicroSD card for a new music player, want to get the best price-per-gig ratio, and want some "hi-res" music, you could do far worse than the 200gig Sandisk Ultra, and far worse than Shopping Square Australia to get it to you. Cheers.

偽物が多いので購入後はサンディスクホームページで製品登録を試しましょう

Reviewed in Japan on 29 June 2019

Capacity: 128GBStyle: Ultra 80Verified Purchase

偽物が多いということで、他の方のレビューを参考にアマゾン配送品（プライム対象）を購入しました。
最安価格より￥100くらい高くなりましたが、それでも格安ですので「やっぱり偽物かもしれない・・・」という不安に駆られ、サンディスクのホームぺージで製品登録してみることにしました。

結果、私の購入品は無事製品登録できましたのでどうやら本物のようです。
不安な方は購入後、製品登録（要アカウント登録）を試してみることをお勧めします。
以下、製品登録の手順です。

製品登録の方法
①サンディスクホームページ右上の「サポート」をクリックして、「サポートオプション」から「製品の登録」を選択。
②「プロダクト」タブを押下して「メモリーカード」を選択。
③「microSD/SDHC/SDXC」「Ultra」「C10（White/Gray/Red text 日本禁止）」「up to 80MB/s (Japan Amazon)」「128GB」を順番に押下して選択。
④「製品コード」欄にmicroSDカード裏に記載のシリアルナンバー(英数１２桁）を入力。
⑤「購買国家」タブを押下し「日本」を選択。
⑥「場所を購入する」タブを押下し、「オンラインショップ」選択すると、すぐ下に新しいタブが現れるので押下し、「Amazon Marketplace」を選択。
⑦「購買年月日」欄のタブを押下し、購入日を入力。
⑧あとは任意入力の項目なのでお好みで入力した後、画面下の「製品を登録」ボタンをクリック。

これで無事製品登録できれば本物です。（偽物だと「既に登録済みの製品です」とはじかれるようです。）
偽物をつかまされたらすぐに返品しましょう！

You can see from the screenshot I linked. The sd card starts corrupting data at 32gbs. This card is clearly a rebranded 32gb card with a false reporting controller. Be careful, test your cards.

Believe the "Fake Card" Hype - Photo to Prove It

Reviewed in the United States on 1 October 2018

Capacity: 200GBStyle: Ultra 100Verified Purchase

Top card doesn't work / Bottom card works. Bought the top card June 18 2018 for a Nintendo Switch and the games would download to 99% and then suddenly I'd get an error. When these cards went on sale recently I bought a new one just to see if it was the card. I could not BELIEVE how different the fonts were! Check out photo. Also the color of the bad card is off (slightly more purple and less red). Sure enough, I was able to download games to the new card without incident. The real product works great but I just can't justify giving 5 stars when I had this experience. Buyer beware!

Class A1 pour une lecture rapide et ouverture des apps plus réactive sur smartphone. Le problème est que j'ai reçue une copie (fake) au lieu de l'originale. Sur l'original, l'opercule de sécurité est blanc, pas transparent et l'adaptateur SD n'a pas de relief (comme montré sur la page de l'article). En copie, les deux photos prises du produit reçu ainsi que la capture de l'adaptateur SD sur la page produit.
