It only takes one sale for the whole month to get back your $25, lol.
It does about 600 TGPs per submit. They have the older service, RS1, which is simpler then RS2 and RS2 which has more features, but is more work to set up. I believe you get access to both so it's your choice which to use. I'm using RS2 these days so I'll talk about that one.
Basically using your browser you upload your html template which is just a no recip gallery that you make and it gives you back a zip archive that contains all your pages with the recips in place. You also have to download the recip zip file that contains all the images for the recips..
After you upload everything to your server you then run the client software on your PC. There are 3 pieces of software.
1) The Auto Submitter, this does most of the submits.
2) The Human Emulator, this loads each submit page in a frame with all the fields pre-filled. This is for the places that do not allow auto submits and use a passphase field that you have to read and fill out. There are less then 20 of these to do on average.
3) Then there is the Auto Confirmer for the e-mails. It catches about 90% of the e-mails and then you run your regular e-mail program to catch the rest.
The traffic is the same as if you had submitted to 600 TGPs by hand. If the big sites pick up your gallery you can get 100k+ in one day. If only the little TGPs pick up your gallery then you are going to only get 3k or so of traffic.
The things I like a lot about the RS is how easy it is to set up and the fact that it hits a ton of the very small TGPs that I would never take the time to hand submit to because they each send very little traffic, but when combined it ads up and often it is better converting traffic.
On the places that do not take a submit each day it will store your submit and only submit the amount that you are allowed under the TGP's rules.
What you are really paying for is the support from Wad & Popeye who keep the database up to date and keep on releasing new versions of the software.
Like I said it's not perfect, but it makes me money. I do about 4 galleries a week using it.
I run a TGP myself and 90% of the submits I get are from the RS and am happy with it from that end as well.
