Leech is a great little app - It's lightweight, fast, stable, and most importantly it just works.

I've repeatedly tried other download managers in the past (Speed download, iGetter, Download Wizard, etc.) and I always found myself uninstalling them because their 'cons' far outweighed any 'pros'. They were everything I didn't want in a download manager: overly complex, clunky, intrusive, required excess system resources, and they were unstable to the point that it even caused other applications to crash.

Pros:
- Lightweight & fast
- Stable
- Automatically integrates with Safari/Firefox's cookies, authenticated sessions, and stored passwords. In other words, downloading files from a website that you're a member of (i.e. a premium RapidShare account) automatically works without you having to mess around with setting up or configuring any tedious rules.
- Plenty of user controllable features & settings (i.e. automatically resize download window, private downloading, user definable rules, etc.)
- It just works.

Cons:
- Doesn't seem to properly work on a couple sites.
- Could use a few more features.

Suggestions:
- It'd be nice if Leech would preserve the "Where from:" URL like Safari does when you download a file. (You can view it in the Finder's "Get Info" window under the "More Info:" tab.)
- Leech (or any download manager for that matter) can always be optimized even further. It'd be great if Leech honed in on maximizing your download speed.

Conclusion:
If you download files on a regular basis (whether it's apps, music, movies, or anything else) I highly recommend you give Leech a try!
