I rate the software as 'good', maybe even 'excellent' but I haven't used the program over a longer time yet so it is too early to tell.
Now another thing is, is it freeware or isn't it? The site says it's free for personal use. The site also says you have to apply for a free license. In order to do that, you have to register as a member on the forum. After logging in, you can fill out the application form.
This is a bit complicated, obviously they don't want to make it too easy to use the software for free.
The problem however is, registering does not work. I have registered twice now, using different email adresses, but never received their confirmation mail.
So I guess there is not much hope that I (or anyone else for that matter) will be able to continue using CDCheck when the 30-day trial period has expired.
Based on this I do not recommend the program. I hate it when people don't do as they say and leave me out to dry.
