Review on Gigastone 16GB 2-Pack Micro SD Card with MicroSD to SD Adapter - Camera Plus, Memory Card for Wyze Cam, Security Camera, Smartphone - Full HD Video Recording, UHS-I U1 C10, up to 85MB/s by Rod Evans

I bought seven of these cards (128GB) which come with a 5 year warranty. Three of them failed within 10 weeks. I tried to contact Gigastone but found that the security certificate on their website had expired over a month ago. I still tried to fill out the online form, only the submit button didn't work. I tried it in two other browsers with the same effect. So I found the email address on the package and contacted the company. I received a response within a reasonable amount of time (perhaps the next business day). The email didn't look like it was written by a native English speaker but I could make it pretty clear that they wanted me to send them a picture of the cards which didn't work to make sure they weren't physical were abused. That seemed perfectly reasonable, so I snapped a photo and responded to the message I received by including an attachment with a picture of the three cards that failed the next day. Примерно через неделю я не получил ответа от компании, поэтому я отправил еще один ответ, спрашивая, получили ли они мое сообщение, или нужна ли им какая-либо дополнительная информация от меня (дополнительные изображения, тесты, которые они хотели, чтобы я провел, etc.). That was over a month ago and I still haven't received a reply or replacement cards. I ended up buying new ones from another company. I'd still like to get replacements (cards worked fine until they stopped, others still seem to be working with no issues at the moment). I don't like leaving negative reviews but I don't seem to hear from the company so I feel it's appropriate to share my experience here.
