Product arrived eventually but the whole process was a headache.

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

Honestly, way too long. 9 days and I had to initiate contact to figure out where it was.

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

Prices are fair-ish. Feels like youre paying a brand-name premium with no brand.

Gotta say, honestly was skeptical at first because the prices seemed almost too good. But nope, product is legit. Got my tracking number within hours and had everything in hand within the week.
