of course diamond is worth it! and you can try it for 30 days, and if you don't like it, get a full refund :)
What kind of member?

I think that unless you seriously intend to follow a program that includes Chess Mentor, you'll be better off (value-wise) by taking the platinum membership.
EDIT: erik has a fair point about the 30 day money-back guarantee.

How can I trie it for 30 days?
You pay and if you don't like, you get your money back.

all new orders are a 30-day money back guarantee. just signup like normal. if you don't like it, cancel, and contact us for a refund.

i don't know why it doesn't work sometimes :( you can contact support and arrange a manual paypal payment.

OK thanks a lot, why can i not pay with paypal?
The first couple of times that I opened the page, the paypal option was absent. Just go in and out of the payment page until it appears.

Diamond membership is a bargain. Support the site we enjoy using. Where else can you get the hours of enjoyment for your dollar that you get here.

The great thing about diamond membership is the variety of quality resources that are available. ChessMentor is a great choice when you really want to buckle down and get to work; it requires less "overhead" than digging the same material out of a book (although I've been known to have a chess set next to the computer). You don't always want to work that hard though. Sometimes you just want to be spoon fed the material and for that the videos are great. Yes you can find videos for free on the web, but they won't be of the same high quality. This isn't to say that there aren't videos that will challenge you to the max and require multiple viewings to understand, but there are some that are just immensely entertaining. I'd pay diamond membership just to watch the videos of Danny Rensch alone. Try it; chances are you'll love the resources that open up to you.
Hello chess-freaks,
I'm thinking to get a membership but don't know what I should take. The full option for 72 euro's a year or another one? Are the features that you have for Diamond membership really that good? Are the video lessons from top players an improvement for my chess game?
Any help or info is welcome....
Thanks a lot..
