**I faced many problems due to solving types of captcha, especially the recaptcha V2 type. The matter was very complicated and was not satisfactory at all, and when I used the Anti-captcha website to help me with that, in fact, it was good at solving it, but the price was very high. I was paying from 0.9-2 dollars for it. Every 1,000 Captcha and it took a lot of time to solve, so that was not suitable for me, so I decided to try another site and found the CaptchaAI site. Honestly, their service was very good for me in many things, including the price. I paid $0.001 for 1,000, and you can also get different solutions. Limited for a very simple monthly subscription. Also, speed and accuracy in solving. The CaptcjaAI website is characterized by speed in solving all types of Captcha, including reCaptchaV2. It was really very good in all of that.**
