I used RosMedia to promote several videos and overall I was satisfied with the results. The interface was easy to understand, registration took just a few minutes, and launching the campaign was straightforward. I especially liked that I could choose the right promotion parameters without spending too much time on setup. The statistics are updated regularly, making it convenient to track effectiveness. Support responds quite quickly and helps with any questions that arise. The cost of services seems reasonable compared to similar platforms. If you need a convenient tool for promoting videos on social media, RosMedia is definitely worth considering. Personally, I had a positive impression.
