This is the first time for him to use the technical assistive tool to read the books and he is really happy for it. I think this desktop magnifier is our right choice.
I use the Zoomax Snow magnifier these two years, which helps me to read whatever is on the books. And I Just tried Aurora HD, this CCTV is also excellent.
This CCTV magnifier is really helpful for reading. The image seems great and it's very easy to use.
