I've been using Bridgit for about a month now. Honestly, I used to actively promote on Instagram, starting with the early versions of Tuligram, and I thought that methods like MF and similar ones were no longer effective. However, it turned out that they still work, and this service confirmed that. I liked the wide functionality, numerous settings for promotion and working with accounts and content. There is the ability to add a large number of accounts, which is very important for me. I don't have to keep track of limits, as the service controls everything itself and does it correctly. Support responds very quickly, which is really great, as many questions arise, and they are resolved quickly. The statistics are pleasing - you can track the number of actions over specific periods, including information about who exactly was followed. As for the downsides, there are sometimes bugs and slowdowns when some account lags in promotion and performs fewer actions than expected. Sometimes accounts would get logged out, but it seems that has been fixed. It's important that support reacts quickly and helps with any issues that arise. Overall, I definitely recommend this service.
