For your use it should be pretty safe then. As for Creality, the couple of printers I've worked with from them are an absolute nightmare (but in their defense it looks like they were discontinued the moment they came out). I have the impression that the only positive comments you get about Creality printers are from people who haven't owned anything else, and joined this "tinkering" circlejerk. They're unpredictable at best and an electrical hazard at worst.
I recommend reading this reddit post and the other (first) post linked there: https://web.archive.org/web/20230119045038/https://www.reddit.com/r/3Dprinting/comments/w7o1pa/stop_recommending_creality_machines_blindly/
