Review on Gigastone 32GB 5-Pack Micro SD Card: Full HD Video, Surveillance Security Cam Action Camera Drone, 90MB/s Micro SDHC UHS-I U1 C10 Class 10 – Enhanced Storage for Multi-purpose Devices by Mark Glass

I only started using these memory cards in September 2021. They are used in the security cameras I use outdoors, replacing memory cards that last 5 years in outdoor conditions. Outside conditions range from -20°F to 100°F and while they won't be exposed to direct rain or snow, they will experience some of that. That devices used indoors were used outdoors for 5 years amazed me. If these memory cards last 5 years I will be very happy.
