Hey guys received my pen but the vial does not connect to the pen in any way. There is no thread on the base of the 3ml push vial and no thread on the end cap of it to screw the needle onto. Maybe I'm not doing something right but everything I have seen and read shows these parts threading together. I was excited to try but guess I'll have to use a normal needle unless I can get some advice.
Happy to change review if rectified
