Worse Instruction booklet I have ever tried to read :(
*UPDATE* Once my friend showed me how simple it is for cartridges, it works great. **I gave it 3-Stars because I have "Heard" great things about this product. However, after owning it for over a week I have still NOT used it. Why? The absolute WORSE instructions I have ever tried to read :( I would love to know who the mental genius is who decided it was a good idea to print tiny light blue instructions on a little dark gray instruction booklet. I needed to put 3.0 Readers over my prescription glasses with a flashlight lighting up the instructions and it still didn't make any sense :( Hopefully, once the friend who recommended this to me shows me how it works, I will be a lot happier. He told me he owns 3 of them.
