Different smells with Air Spencer?

[hellfreeze]

I've been a fan of Giga Air Spencer Squash scent for years, and recently thought I would try the CS-X3 version to see if the smell lasts longer. The smell doesn't seem the same as the clip on ones. Did I get a bunk unit, or is this how it is?

Here's a link for the stuff, in case anyone needs pictures:
