Travel Technology - errorFix, good idea to use it?

Recently a friend mention this registry repair utility. I downloaded it but have not yet used it. I note that it has various tools to: scan; clean; backup; optimizer; error repair; tweak memory etc....
It seems like it has everything in one place. Is it a good package of utilities to use? Care to share your opinion and experience? Thanks.

CNET is a good source to find free registry fix software with trusted recommendations. I note that errorFix isn't even on their list.

Also, CCleaner is what I use and it's been stable and good for many years and near-continuous upgrades.
