Filament not sticking to itself sounds pretty unusual… Found this review on youtube. The channel has 6 subscribers and I have no idea if it’s legit or disguised marketing, but all the comments mention similar problems as yours. There’s also this review, with more negative comments. One person says they managed to get good prints by raising the print temp even more, but don’t do that if you have a PTFE lined hotend. I.e. only try higher temps if you know for sure that you have an all metal hotend.
