Review on 📷 Gigastone 64GB SD Card V30 SDXC Memory Card - High Speed 4K Ultra HD UHD Video Compatible with Canon Nikon Sony Pentax Kodak Olympus Panasonic Digital Camera by Calvin Chavva

The price was great. The product was mediocre at best from a company I wasn't familiar with but risked. I ordered two SD cards. One worked exactly as I wanted and expected. Another decided to change the format of some images himself, which made me lose about a quarter of my images. Then he decided not to support my format at all. Luckily I've already downloaded everything I could. My suggestion is to buy from a company with an established track record. It will cost a bit more, but apparently you get what you pay for when it comes to SD cards.
