infinum reviewed FreeFileSync:

Absolute best. I wish I could point to some issues but I can not think of any major flaws. One minor is that there is no ability to choose the installation language and so it forces an auto-detected language but that is all. Great app.

An excellent program with several unique features of its own. Can handle some stuff that even some fully commercial products can't.
Zenju is very responsive to queries, active in the help forums and always striving to make it better. What more can we ask? I like it so much I've hit up Paypal and sent him some cash. Well worth it.

Peri reviewed FreeFileSync:

Awesome and reliable sync software you can count on. I've been using it for more than 3 years now. Best I have used so far for syncing.

akya reviewed FreeFileSync:

Probably the best open source software that I have ever encountered. :) Keep up the good work!
