I had been using Transmit for some time but got increasingly frustrated because it did not always transfer files in sub-folders accurately. There's always be one or two with 0 bytes, for example, or only half the files showing on the server.

As I host and maintain a number of blog-driven sites, updating Expression Engine and Wordpress sites was becoming a big pain as I'd have to cross check folder after folder.

I tested an update with Yummy on one site and it simply did the job. It has since performed flawlessly. I can actually 'trust' it.

The developer's feedback and response is always positive and prompt.
