+One thing I will say about RK is that they leave few stones unturned when it comes to porn. They have the standard sites that you would expect from a network like this, but they throw in a few surprises like a squirting site, "joke" site (It's Real) and even a tranny site if you want something outside of the typical offerings.
+All of the videos are filmed very well and the quality of the downloads is very high. Some of the POV scenes are a little rough and/or poorly lit, but I imagine that is part of the "look." The videos also do a nice job of putting forth enough of a "story" to make it entertaining, but not losing sight of the fact that it is porn.
+There are lots of attractive women on this site that cross quite a range. I was able to find most of my Euro favorites from previous memberships to those sites as well as many American women as well. There is a fair amount of silicone (which is not necessarily my cup of tea) on the MILF models, but it is not very widespread through all of the models.
-The file sizes are large. I know space is cheap, but the shortest videos are 25ish minutes and those take up 2GB. After being a member of other sites with equivalent video quality at half the size, I believe this is something that can be improved.
-While I normally anticipate ads when joining a site, one of the things that annoyed me about RK was that they would put in scenes for other sites mixed in with some of their scenes. More than once, I clicked on an update to be redirected to a "join" page for a partner site.
-Some of the sites are on a monthly or a "whenever" update schedule, which is disappointing and frustrating. They might have 20 active sites, but only 7-10 update in a way that you know you will have a weekly update.
-Search function is nothing special. For a general search (click on a type), you can pick one element and go from there. Their "Search" function (type in something) is nice if you know the name, as it will auto-fill, but you have to have a good idea of the name.
-The big gorilla: download limits. The TOS has a data limit of (I believe) 5GB OR 15 "Big" movies. A "big" movie from what I saw is an HD movie of 720 or 1080 quality, as the filename is "blahblah_big.avi," so you can download 15 of those in a day. I am not a site ripper, but instead download movies that I like, so I never had an issue with the download limits and never received a message that I went over my limit despite downloading over 400GB over the course of a month.
While it appears that the cons outweigh the pros, I found most of the cons to be fairly minor in comparison to the high-quality porn that this site provided. This site is top 2 when it comes to downloaded videos over the course of a month and I have not "tired" of them as I have with some of the other sites. I definitely recommend this site, especially with some of the deals that can be had.
