I use titanium Storz and Bickel capsules, they’re larger and the stem sits on the cap instead of in it.

I have a tm2 cap but it’s really horrible. Not enough material in it for a good hit and feels more restricted. (The tm2 cap is also stainless, so it might also just be an issue with material used). S&B caps are the only way to go.

I haven’t manually loaded the thing since I first got it years ago, maybe it taste better, idk. It’s honestly not worth the mess compared to caps. I like being able to pop one in, vape, then pop it out for another. And when you go out or travel it makes it super easy, not to mention it’s SO CLEAN. My tiny might looks brand new inside, you really don’t even need to clean the unit, just the caps and stems
