Well, I'm no longer in my 30s, but I will jump in anyhow.

This is my second time as a member. When I first joined, I was 39. After having involved communication with and/or going on dates with a few men for a year and a half, I met (while 40) a man I subsequently got engaged to. I had had offers to marry before, but this was the first I had accepted. So I would consider that a success (even though I eventually called off the engagement). I'll note that I was simultaneously a member on Match.com, where I got more initial overtures but about the same number of "quality" dates on both (making the "yield" on eH better).

I am now 42. Since rejoining a couple of months ago, I have gone on varying numbers of actual dates with three men from eH, and have had communication initiated (getting to various stages) by at least 20 or 30 others. Not being privy to other womens' stats, I can't judge whether I have "more" trouble due to age than I would either without it listed or if I were younger, but based upon all kinds of things I read on the message boards, I think that is a decent result, and as good a rate as I get in the world at large. I think many men in their 40s and early 50s want to date women in their 20s to mid 30s. Don't know if you ever saw the Bravo show Millionaire Matchmaker, but I found it hilarious (and pathetic) that most of the men over 40 were obsessed with dating a woman under 30, for reasons having nothing to do with children, such that the Matchmaker counseled her women not to reveal their ages. I have a wide age setting for matches, and it is definitely the case that more older men are interested. But one of my 3 eH dates is my age and I recently went out with a non eH guy a year younger, so there are no absolutes. FWIW, several men I have dealt with claim to be open to the idea of expanding their families. I have several girlfriends who had their first children at 38 and up.

I guess expectations have a lot to do with how easy it feels. I remind myself that it only takes one match with the right guy to get what you want, and that it will happen at the right time, so the number of failures doesn't really matter. That said, I still think this process sucks.

I am universally told that I look younger than I am, so I'm guessing that without age posted I might get more interest from those who are determined to date someone below a certain cutoff, but who knows. I agree with the consensus here that a lie about anything would be a disaster.
