I've been using this service for a year now and can't imagine how I managed without it before. Everything works quickly and clearly, no confusion at all. Messages come and go instantly, clients are happy, even thanking us for the quick response. Sales have also increased. I haven't noticed any errors, but it's important to carefully read the instructions and set everything up according to the recommendations. If any questions arise, customer support is always available — we've reached out a few times, and the communication was pleasant.
