Easy to Use
In terms of ease of use, you're not going to face any trouble whatsoever; as it seems that the developers have worked a great deal to create a responsive website design. It means that you can access it easily through your desktop as well as mobile devices.
The mobile version is fully optimized for users to sign up and explore on the go. The only issue you might experience here is that unlike many other dating sites these days; Iwantblacks.com doesn't have a mobile app available yet.
Search Functions
After creating the profile, you can search the database in many ways. The basic search criteria include age, gender, and members with a photo only. It is also possible to find members who are online at that moment.
You can also use the extended search feature and use specific criteria – you can search members by city or username. Regional searches really help you find a better match. Interestingly, it is possible to block certain members from contacting you, which comes in handy when you start receiving too many responses.
Safety & Security
It seems that this dating site is concerned about maintaining the security of its members' profiles, which is why no one can see them unless they've registered and subscribed to a plan.
You don't need to worry too much about losing your private details, even when you're connected with someone through their chat room feature, as data goes through an SSL connection, so it is tough to intercept those messages.
To ensure you receive quality service, they also take action to prevent fake IDs. For this, the site requires every user to confirm the email address. Moreover, every picture a member uploads goes through a moderator who checks it and approves it to become visible on the site. It means that you won't find profiles with celebrity pictures or those of cartoon characters.
One issue you might experience is that there's no way to hide your pictures from other members. The site lets you upload a series of pictures, and other members can check them all after they've paid and signed up.
Summary
Overall, Iwantblacks.com is a reasonably good site with relatively genuine profiles. Yes, it requires you to pay upfront, but it is possible to find a trial plan before you commit to anything. Customer service could've been better, but it's the same story with most dating sites. Learn to use it correctly, and you might end up meeting someone special.
