Joined recently to check those out, here is my unbiased review.
The sites are NOT bad at all. I suspect both sites have the same owners, as the script is the same, they are interlinked and many profiles are on both sites (though a registration on one doesn't automatically transfer your profile to another).
Pros: the sites have a lot of real Russian women, especially in their 30s and 40's. The autmosphere on the sites is rather relaxed, just like on loveplanet.ru, which I DO recommend. Many not so young real Russian ladies are not afraid to flirt and make the first move. If you are somewhat attractive man you will get attention. And the sites are absolutely free.
Cons: there ARE scammers on both sites. Especially from Ukraine (translation scams). Though they are everywhere, aren't they? You will get few messages from scammers. But those are easy to spot. If a girl drops you her e-mail address in the very first message, especially in the hidden form like " at Rambler dot ru", this is a scam. Please, please don't reply!
Overall: the sites are probably not very suitable for baiting, unless you directly contact profiles with known scammy pictures. But if you are searching for a Russian woman, especially if you are a serious man, don't mind a woman closer to your age in her 30's-40's, and are not obsessed with finding a 20 year old beauty, you can give it a try. Definately better than all these scammy expensive marriage agencies.
