  • SanDisk Ultra Dual Drive m3.0 32GB

  • Not reliable

    from Mississauga, Ontario, Canada on April 14, 2019

    It stopped working in less than 6 months with minimal use. I only used the USB side of it, never tested the micro USB.

  • Works really well, but it's SO poorly designed!

    from London, ON on January 3, 2018

    I have many gripes with the way this product was designed and manufactured. 1st of all, this thing is about the size of an adult's toe. It's really small and easy to lose. Make sure your child, cat, dog or vacuum doesn’t swallow it. The casing has an area on the side for you to put a lanyard but they were too cheap to even give you a lanyard. 2nd of all, the casing is another problem when you are plugging it into a laptop because laptops have USB ports side by side and the spacing between the USB ports aren't that wide. The side of the casing sticks out and takes up space on the laptop port. I can't plug this and a USB cable side by side. 3rd of all, the design is interesting, in that you can slide it back and forth to use it as Micro-USB or USB 3.0 drive... It's kind of sexual... resembles a penis going in and out. This part I like. My gripe with it is that there's no plastic covering on the top and bottom! It's hollow and your finger gets stuck in between when you slide it back and forth. And when you plug it into a port, you have to firmly hold onto the slider or it won't get plugged into the port. It's so annoying that the slider doesn't lock into place. 4th of all, make sure your Android phone supports USB OTG (USB On-The-Go). The Micro-USB works well with my Samsung Galaxy Note 4, but I don’t know about your Android phone, so you should check it before you buy it. My gripe is with the Sandisk app that’s preloaded onto the drive. It's not the most user-friendly app to use. You have to know how to navigate deep into your phone to copy files. It's a lot like using Windows Explorer and dealing with folders after folders. And another gripe I have is that the app doesn't have a dismount feature! If you unplug the drive from your phone without dismounting it, it could damage the drive in the future. Because it doesn’t have a dismount feature that I know of, I always have to shut down my phone, unplug it and then restart my phone. This process sucks. I hate restarting my phone. It drains battery. That’s all for now. I love it otherwise.
