Big questions about Dual-chamber Disposable- flavor cross-contamination

Hey everyone,
I work in vaping hardware, and I need your honest input on dual-tank systems.

The Big Question
Is flavor cross-contamination actually ruining the dual-tank experience for you?
You know the scenario - you want coffee in the morning and fruit in the afternoon without swapping devices. But if your flavors keep mixing, does the whole concept fall apart?

I’m curious:

Are you getting noticeable flavor bleed between tanks?
Does it happen right away or take time?
Have you found any fixes, or did you just abandon dual-tanks completely?

But What If That’s Not Even The Real Problem?
When you actually use dual-tank disposable, what bugs you most?

Why I’m Asking
We’re developing new products and want to solve actual problems, not create more shelf-decorations.
Drop your real experience below - whether you love dual-tanks, hate them, or gave up on them entirely. The brutal truth helps more than polite feedback. Thank you!

Almost every dual tank i have seen has two flavors that compliment each other, the biggest benefit to a dual tank is the ability to mix the two tanks in one hit.

Putting two non complimenting flavors in one unit defeats the best feature of the dual tank style devices.

I like dual chamber vape’s design. But never have a chance to try it…

Agree with your point. Special attention also needs to be paid to the details of flavor combinations. This requires professional oil testing
