One of the best features Chemistry.com has compared to others is matching you with others who share your preferences.

Another great feature of Chemistry.com is that you have the ability to see who looked at your profile. You can view all the profiles of singles that checked you out by clicking on the "interested in you" link.

You will receive email matches and be able to read the profile of other members and see photos of them.

Compatibility and chemistry are large parts of human attraction and the beginning of a successful relationship.

Here are the pros and cons of Chemistry.com.

Pros:

• Photo profiles
• Compatible match-making system based on your honest answers
• Secure email
• Advice articles and helpful dating tips

Cons:

• Expensive monthly payment
• Third-party advertising via email and throughout the web site
• Cannot search for matches, you can only rate the ones you have been assigned from Chemistry.com

There are usually promotions available on the web site for other features, but there are usually not promotions or discounts for signing up. You can sign up for a 7 day trial and try to find a match in that time, but you can only do this once. Here are some user reviews of Chemistry.com:

"I wanted to try out Chemistry.com to see if the site lived up to the advertising hype. Unfortunately, it didn't. Here's why: You are limited to viewing 5 matches a day, so if you find the ones presented to you to not be appropriate you have to wait to receive more matches. You are given a Chemistry Profile based on a series of questions. This profile (major and minor personality types) is then used as part of the matching criteria. Your profile description includes rankings of which personality types match best with you. So I was surprise to find men with each of the different personality types all described to me as a "Great Match". It does not seem that the Chemistry Profile holds the necessary weight in selecting matches. Especially, as the men I found the most interesting WERE the ones, according to my chemistry profile description, which were considered the best match. This may seem minor, but what ended up really irking me was the large number of matches who seemed illiterate or extremely careless in typing. These were discounted immediately (and I saw 2-3 of these a day!) I recommend if you are trying to find a mate that you use a spell-checker, or better yet, have a friend review your statement. I had paid a premium to join Chemistry.com believing that their matching criteria would be more accurate. I was sorely disappointed to find it was not." - Female, Age 39

"Chemistry.com is an offshoot of Match.com, set up to be like eHarmony.com. After more than two months of usage, my biggest observation is that Match has given away many free memberships to its female subscribers so they can use Chemistry.com . Many of the "New Matches" end up being inactive profiles of Match.com users. They promise that you will have three meetings or you get three more months free. Not sure I'm that interested at this point in more inactive profiles. They are also suppose to gather info from who you make active or who you archive, however, it seems to be bunk, as I'm always getting profiles without pictures, wrong race, too far away and body shape. My recommendation to other men.... don't waste your money, stay with a site where you can pick your matches and know that the gals are active on the site, also you get five matches per day and they don't update the site until late in the morning, it should happen overnight, a bit annoying." - Male, Age 36
