Already using this service for 2 month for buying retention views. This service work well. It help me to ranking videos. We must learn about youtube algorithm by practicing if want to use any SMM panel, sometime the retention views are not enable or maintenance, so i choose other available options. Also important to choose refill-guarantee to avoid drop. Never have any problem with this service. Overall i like it. I hope i stay using this service for long as i can for my long term project. And because retention are important, i hope YTbot can give us more minutes retention and the service keep active! Thank you!
