It just works...

I popped this in my new Moto G5 Plus phone, it just works. My 32GGB memory phone is now 160GB, just like that.

  • from Toronto, ON

Not so great in Read/Write

The speed is not that great for reading writing to the SD. Copied 32 GB of data to the SD card, it took what seems like forever to copy.

  • from Fredericton, NB

Great extra storage

I use this card in conjunction with my iKlips Wizard to add memory for both iPhone (64GB) and iPad (32GB). Great for long trips, load a bunch of shows to the card and away I go. ;)

  • from Winnipeg

Excellent Value

Purchased these for my new phones. Installed and phones setup automatically. Best price around for this size of unit. I would recommend this item.

  • from Calgary, AB

No Issues

When I needed to find a memory card for my phone, I first came to the Best Buy website and based on the reviews I bought this card. I have had no issues and installation was easy. Thanks Best Buy!

I bought this chip on sale, the sale price was too good to be true! Unfortunately, it keeps "dismounting" and becoming unreadable for every single thing I have tried to use it for (two different smart phones, and a DSLR). I may have gotten a crappy chip somehow. Unfortunately I am well past the cut-off for returns. I'm sticking to Lexar and Sandisk next time.

  • from Montreal

Works great in my phone

Put it in Moto G5. Works. Great. Super.

Best memory card you're going to buy for any amount of money.

This memory card has been the best memory card I've ever owned. I have never gotten a single error in any of my files it's fast in both read and write speed. I have owed SanDisk memory cards and have had nothing but problems with errors with that brand of cards and a lot of my friends have said the same thing just make sure the device you're buying is capable of handling a memory card this size.

  • from Regina, SK

Good Card for the SALE price

Quite fast, reliable and good bang for the buck

  • from Vancouver, BC

Good product

This Micro SD card work well in my phone and in my tablet. Fast and lots of storage capacity. The brand is unknown to me but it works just as well the other well known brands.

  • from Cambridge, ON

No issue

recognized on both devices

  • from Calgary, AB


Works great in my Samsung S7-Edge! Pictures capture well and is comparable to higher cost brands.

Product is as described; great value

I was looking for a micro card for my (cheap) smartphone which comes with almost no memory. I didn't want to spend more on the card than on the phone which is why this product seemed to be such great value. I was confident selecting this product because so many other reviews were high, and I would have to agree. Now, I haven't worked with many micro cards so it's difficult for me to compare this to another product but I can say that it worked just fine in my Samsung smartphone which is running Android Marshmallow and as soon as I plugged it in, the OS recognized it and asked me if I wanted it to be the default storage. Shortly after, I transferred all the info from my old iPhone which included all my photos and songs (1000+ total) plus app info. I've had the card for a few weeks and use my phone a light to average amount. I've never had an issue saving or retrieving information. I've never seen a pause, a glitch, or a hiccup. I can't tell the difference between when the phone saves to internal memory versus the card. If I can't tell that it's working, I think that's fast enough for me. So overall, I agree with the majority of ratings which are excellent: I get way more storage than I'll probably ever need for WAY less than half the price. A family member just bought my same phone and I will be buying another SP micro SD card for them.

Great Card

After copying my music onto it, I popped it into my new Samsung Galaxy phone and it works great! No formatting etc. Seems like a great buy for the price after a couple of weeks of usage!

  • from Châteauguay, QC

Good product

Very good product for the price, I definitely recommand it.

  • from Langley

Great Product!

Bought it for my Samsung Tab A. So far works great and it arrived really quick. Definitely worth the price tag.

  • from Thornhill

Great works!

Worked flawlessly, for the price it was a great value compared to the big names.

  • from Montreal, QC

Don't waste your money spending premiums for higher priced cards

Get this one, if 4k video recording isn't important to you, but storage, fast read speeds and reliability is, then this card is for you. Don't spend another hundred or so for a Sandisk, which normally you can buy from others for half the price than best buy, but if you're in the store and need a cheap fast microsd card without having to mention the price match, get this! you won't be disappointed.

  • from Dartmouth, NS

Works great in my S5 Neo

A really good 128GB micro SD at a very reasonable price. Lots of storage for pictures, music and videos. Very fast access.

  • from Bayview, ON

Good Capacity and performance

Recommended by my friend this brand and after i purchased and tried, it satisfied my expectations.

  • from Montréal, QC

Works fine

The card was as expected, it even fitted inside the card slot of my cell phone! It has the capacity advertized for and I like it because it sits inside the phone and don't worry about not seeing it, it is still there!
