This is a great product, an absolute must for those who want to run a Mac OS X server on a limited internet pipe. But if you don't like spending a day or more troubleshooting the program to try and get it to work this isn't for you...this wouldn't have been a problem if the support actually existed. There is NO support, I emailed them during business hours and got no reply. When I paid for the pro version of throttled I didn't even get my serial # until I did a whois on their domain and called them...if you rely on support then you may find it worth your time to avoid this product and all products this company makes as there is NO SUPPORT! But other then that this product is great, just takes some time getting used to how it works. TIP: If you have something like a FTP server which consumes a huge amount of ports like I did and which results in the throttled port being in use you will not be able to use the gui. Instead you will have to download the command prompt version, create the ipfw rules yourself and then start the throttled process yourself. It's not that hard if you don't mind reading the documentation and startup script for info on how to do both...

But again there is no support and since they seem to promise support this is a big no no to me...is anyone there?!
