Please help me find a vape and juice in the US

I just moved back to the US after 13 years in South Korea, where I started vaping.

When I started I got a vape I loved and just regularly replaced it whenever the battery started to go. I had vape juice I liked, and it was just easy, I'd walk into my vape shop and be automatically handed another bottle and a new coil. So I never really learned much or had to think too hard.

This is my vape and what I've been using (I really don't know if I was using something terrible or lame or I don't know, so please don't judge too harshly)

I've finally run out, and my battery is going, so I headed over to my local shop thinking it would be no problem. I was very wrong.

My first mistake was trying disposable, but I was trying to save some money. I bought two and they are SO SWEET and just feel like they're literally coating my mouth in gross flavor.

What I smoked before was technically "triple berry" flavor, but it was mostly a flavorless smooth smoke with a faint hint at the end that was never even a little bit sweet. I'm not picky about flavor, but I am picky about the experience.

Please help me. Does that vape juice exist in the US? I dont have the box for my vape any more, has anyone seen it or one like it, or could you recommend something?

I would really appreciate any suggestions. I've done a Lot of googling, but it's hard to know what info to follow and what to ignore since both disposables I bought are really liked online.
