Today, Amazon has the 128GB micro SD card on sale for just $109.99. It’s regular price is $130. So it’s not a huge deal, but it is definitely pretty nice. I have this same 128GB microSD card in my LG G3 and love it. It’s great for recording 4K video on devices like the Galaxy S5, Galaxy Note 4, and even the LG G3. Up To 48MB/s Read Speed. 10-Year Warranty. Easily Back Up Files With “SanDisk Memory Zone” App. Includes SD Adapter.
