Its a great matrimonial website which runs globally but it needs very big amount to upgrade from free user to premium user, a free user cant do anything apart from free signup and login.
After login you can only serach and see yours daily matches, but you cant interact with them in any kind before upgradation to as premium member.
For becoming a premium member it demands 1500-3000 per month according to plan choose(i think its big amount to invest, it should be 300-500 per month), i think shaadi.com should gives a free trial for minimum 30 days to all its members for trying it out shaadi.com in whole, i think thats the only demerit I find in shaadi.com yet, if they fix that issue I will give it 10 out of 10, but 4 for now.
