Product arrived eventually but the whole process was a headache.
quality

Product doesnt inspire confidence. Color is off, smell is funky, effects are minimal.
delivery

Honestly, way too long. 9 days and I had to initiate contact to figure out where it was.
service
★ ★ ☆ ☆ ☆
Long story short, took 4 days to hear back. By then the issue had resolved itself.

Way too expensive for inconsistent quality. Not worth it.

Service is slow. Not terrible but expected faster responses.
pricing

Middle of the road vendor. Not bad enough to warn people away from but not good enough to recommend either. Could go either way honestly.

Long story short, tried to get help with a problem and the response was dismissive. Not great.
