It is best for your Android OS based smartphone and tablets. I am using this SanDisk Ultra 128GB micro SDXC card for 8 months and my experience is very good. Very good transfer speeds- up to 100MB per second. It has faster app performance and UHS speed is class U1 and during video recording playback speed class 10. It is shockproof, temperature resistance, waterproof and x-ray-proof. The company gives you a limited manufacturer warranty. You can buy it without any hesitation.
