if you read my last post I was worried about filing up the 16gb internal flash on my Breeze Drone. I bought myself a HooToo from Amazon and added a 128GB flash drive to is, then when the videos are on my phone and filling it up, I can just wirelessly transfer them to my USB stick which is in my HooToo, hence freeing space up on my phone and I can then format my drone and having a continuous 16gb of internal flash memory. The HooToo does a lot more than transfer files wirelessly but that's mainly what I will be using it for, I have LOTS OF cameras, all with built in WiFi so this little device will be great for a back up on the fly while I'm on holidays. Great piece of kit. YouTube it to see if its of any use to anyone else.
