I used this during practical training in my student days, but I haven't actually used it in a clinical setting. There are no issues with its use; the needle doesn't slip, and the lock doesn't come undone. It is unsterilized, but I have wiped and disinfected it with alcohol swabs. *Regarding the condition, this is based on my personal assessment, so please be sure to check the photos.
