I bought an Arbhar from user @jotaha. The box arrived damaged, which would usually be alright if the module had been packed properly. Unfortunately that wasn't the case: instead of putting the module's box in a larger box with enough padding in between, which is in my experience common practice, he simply wrapped the original box in paper. Of course that wasn't enough protection and the module arrived broken.
Hopefully that won't happen again but I definitely wouldn't take the risk and avoid trading with him.
