[EX Q]: Just opened my plastic package because hard to see if center pin was copper as pictured in ad.. sadly it was not. By the way, do not tear open your package because it states on the package,"No returns if bag is open" what a waste, I should have just driven to an autoparts store.
[EX A]: negative

[EX Q]: Love this fragrance for the past 40+ years, now very hard to find...this is my 2nd reorder and Ill always come back here for perfect transaction, fast delivery and great price.♥
[EX A]: positive

[EX Q]: Compatible with Raspberry Pi/linux but when I wanted to use the alternate power method I noticed it was missing battery contacts for AAA batteries so there was no way to use them instead of rechargeable pack. Digital button input always got stuck and spammed the same key about 10x.
[EX A]:
negative
