It is great to use with my Laptop but I would love to be able to use it with my iPhone too but it doesn’t work with that. Is there a good reason for this?
I couldn't believe how expensive these little machines are so when I found this Brother, I didn't know whether to take a chance on it as it's an older model. Still, it was also much cheaper than newer models. The bottom line is that I'm very glad I bought it. There's no instructions included, except to download the accompanying software online. Thankfully it was easy to do and one of those apps proved to be excellent at reading faded receipts through the scanner. Once I played around with all the settings and found what worked, I was so relieved I hadn't wasted my money. Happy camper in the end.
