I haven't actually used them, but I can lay some facts and opinions bare so they can perhaps help you move closer to making up your mind about them:

Good signs:

1.They have been around for close to a decade, so clearly they wouldn't want to mess whatever reputation they have built so far by providing poor service.

2.They don't lie about how long they've been around.

3.They offer tutoring and not just writing services. It even appears tutoring is their bread and butter. This is a good sign since the dynamics of tutoring, besides not being as attractive to lazy and greedy hawkers of student services, also make it harder to swindle clients.

4.Their site is free of superfluous promises and guarantees like most other scam sites run by inept scammers. They also hardly feel the need to market themselves.

5.They have a strong and long-standing social media presence. This is often a good pointer as it could be taken to indicate approval and trust by previous users.

Cause for concern:

1.They have only been around for a decade. As much as that differentiates them from the other hundreds of dubious operators in this industry, it also doesn't put them in the class of the veterans and real guarantees.

2.Their registration is private. This is not exactly a bad sign. It actually protects the owner from phishing and spamming. But if open and complete disclosure was their policy, they would go with public display of registration particulars instead of hiding under privacy protection.

Hopefully this will be somewhat helpful.
