1. Company's reputation and word of mouth: Understand the company's background and history, find customers' comments and feedback, and judge its reputation and word of mouth.

2. Professional qualifications and experience: confirm whether the company has professional qualifications and experience related to trademark registration, such as registered agent qualification, legal background or professional knowledge in related fields.

3. Service content and scope: Understand the content and scope of the trademark registration service provided by the company, ensure that it can meet your needs and provide comprehensive service support.

4. Price transparency: verify whether the charging method and price of the company are transparent, and whether there are hidden charges or extra charges.

5. Legality and compliance: Ensure that the company complies with relevant laws, regulations and rules in the process of trademark registration.

I suggest that you make a full investigation and comparison before choosing a trademark registrar to ensure that the service provider you choose is reliable and suitable.

Please note that this is only a general suggestion. You'd better study and evaluate the reliability of "Mark Ape" or other trademark registrars yourself, and consult professional legal advice if necessary.
