Review on 💾 High Speed Gigastone 128GB SDXC Memory Card: Ideal for 4K Ultra HD Video, Compatible with Canon, Nikon, Sony, Pentax, Kodak, Olympus, Panasonic Digital Cameras by Eric Cooper

The price was excellent. The product was mediocre at best from a company I was unfamiliar 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.
