I bought a Children's Orthodontics course for 14,000, instead of calmly watching them with a cup of coffee ... I watched them through a video editor to compare pictures and voice acting, that is, no one in any way watched them even cursorily before selling!!!! The horror!
I bought participation in a series of "webinars" by the famous Dr. Alladin Sabbagh. It turned out that access was not given to webinars, but to a pre-recorded video. Thus, the participants were deprived of live communication with the author, the opportunity to quickly get answers to questions. The organizers promised to convey the wishes of the participants to the author, but no interactions occurred ... The author also recorded a video in English, the video was translated. It was the most disgusting translation: incoherent sentences and even words, thoughts were lost in the course of the sentence. Sometimes there was a feeling that the translation was recorded by a completely incompetent student in dentistry, using a Google translator, and he recorded it in between classes on his iPhone headset (extraneous noise on the recording). Besides, I never got the recording of the third video.… In general, I express the hope that this was the only such crooked "webinar" and I was just unlucky. I wish the organizers, first of all, to honestly sell their information products and fulfill their obligations to provide content, as well as to improve the level of their translators, and to establish the technical part of their site.
