I use the iXpand every day to backup photos on my iPhone and iPad. I can also use the device to transfer photos to my computer using the USB connection. When you are in the field, you can easily backup your photos in seconds. You never want to take photos on a huge inspection or property preservation and job and then have your phone crash … maybe when it gets dropped … you sit on it … or it flies off the car dash because of a quick stop. Always have a backup. That 75 yards of debris is in the landfill and you lost all of your iPhone photos that document the completed task. No photos … guess what? … you don’t get paid for your hard work.
